Central America Weather & Natural Hazards Today: Pacific Tropical Disturbance Brings Heavy Rain, Flooding and Landslide Threats

Saturday, November 7, 2026 | Orbis Weather

By Paul Harrison | Orbis Weather

CENTRAL AMERICA — A broad area of low pressure over the eastern Pacific is bringing a potentially dangerous combination of heavy tropical rainfall, thunderstorms and flooding risks to parts of Central America this weekend, with Nicaragua and Costa Rica among the countries requiring the closest attention.

The National Hurricane Center (NHC) reports that a disturbance offshore of Central America has a 30% probability of developing into a tropical cyclone during the next 48 hours and the next seven days.

Although the likelihood of tropical development has decreased, the system is still capable of producing significant rainfall. The NHC specifically warns that heavy rain could affect portions of Central America throughout the weekend.

Costa Rica’s National Meteorological Institute (IMN) forecasts continued unstable weather on Saturday, particularly along the Pacific coast. Meanwhile, Panama’s civil protection agency has recently highlighted significant rainfall risks in central and western parts of the country.

The greatest immediate concern is not necessarily the formation of a named tropical storm. It is the possibility that repeated heavy downpours could overwhelm drainage systems, raise rivers and destabilize hillsides.

Today’s Main Weather Headlines

• 🌧️ Nicaragua: Heavy rainfall associated with the offshore Pacific disturbance raises concerns about flash flooding and landslides.

• ⛈️ Costa Rica: A nearby low-pressure system is expected to maintain widespread atmospheric instability, with rain particularly affecting Pacific-facing regions.

• 🌊 Panama: Recent significant-rainfall advisories highlight flood-prone communities in western and central provinces.

• 🌦️ Honduras: Localized heavy showers, thunderstorms and flooding remain hazards to monitor.

• 🌩️ El Salvador: Mountainous communities and Pacific coastal areas should watch for changes in rainfall intensity.

• 🌫️ Guatemala: Cooler highland mornings, fog and localized rainfall remain important seasonal considerations.

• 🌤️ Belize: Caribbean showers and localized thunderstorms are possible, although the main Pacific disturbance is farther south.

• 🌀 Eastern Pacific: Tropical cyclone formation probability is low at 30%, but heavy rain remains possible even without tropical development.

These headlines distinguish confirmed regional forecasts from potential hazards. They do not mean that every country is experiencing severe weather or has an active national warning.

1. Eastern Pacific Tropical Disturbance: Development Chances Decrease

The main tropical weather feature affecting Central America is a broad area of low pressure located offshore of the region’s Pacific coast.

According to the National Hurricane Center’s latest available tropical weather outlook, issued at 10:00 p.m. Pacific Standard Time on Friday, November 6, the system continues producing a large area of showers and thunderstorms.

Environmental conditions remain marginally favorable for additional organization through Sunday. However, strengthening upper-level winds are expected to reduce the likelihood of tropical cyclone development early next week.

The NHC had not classified this disturbance as a tropical depression or tropical storm in the referenced advisory.

The Atlantic basin, including the Caribbean Sea and Gulf of Mexico, also had no active tropical cyclones at the time of the early November 7 NHC update.

Why the disturbance still matters

Even without a closed tropical circulation or named storm, a broad low-pressure system can transport substantial tropical moisture into Central America.

When moist air rises over mountainous terrain, rainfall can intensify. Repeated thunderstorms over the same watersheds can cause rapid river rises, flash flooding and landslides.

The system’s precise organization is therefore less important to immediate public safety than the location, intensity and duration of its rainfall.

2. Nicaragua: Heavy Rain and Flash-Flooding Concerns

Nicaragua remains one of the countries most exposed to the Pacific disturbance.

The country’s proximity to the offshore low-pressure system makes changes in thunderstorm organization and rainfall distribution particularly important.

Western and southern Nicaragua deserve attention, especially where steep terrain, rivers and vulnerable roads intersect.

Main hazards

Heavy rainfall: Persistent showers and thunderstorms could produce substantial local accumulations, particularly where rain bands repeatedly affect the same communities.

Flash flooding: Smaller rivers, streams and urban drainage channels may respond quickly to intense rainfall.

Landslides: Mountain roads and unstable slopes could become dangerous following prolonged rainfall.

Travel disruption: Heavy downpours can reduce visibility, damage unpaved roads and temporarily isolate communities.

Orbis Weather assessment

Rainfall and flooding remain the primary concerns for Nicaragua this weekend. However, the precise distribution of the heaviest rain remains uncertain, and no nationwide rainfall total or new emergency declaration has been independently confirmed for this edition.

Residents should follow Nicaragua’s national disaster management agency, SINAPRED, and the national meteorological service, INETER, for local warnings.

3. Costa Rica: Pacific Coast Faces Continued Unstable Weather

Costa Rica’s National Meteorological Institute has issued a forecast for Saturday, November 7, highlighting the influence of a low-pressure system near the Pacific coasts of northern Costa Rica and Nicaragua.

The IMN expects unstable conditions to continue throughout the day.

Rain and showers are anticipated over offshore waters during the early morning, followed by rainfall along western coastal areas of the Northern and Central Pacific regions.

By early afternoon, additional moisture is expected to generate scattered showers and downpours across Pacific-facing districts.

Isolated heavy showers, potentially accompanied by thunderstorms, are also forecast along the Caribbean slope and the central-northern Northern Zone.

Areas to monitor

Northern Pacific: Coastal communities and nearby mountain districts could experience repeated periods of rain.

Central Pacific: Additional afternoon rainfall may affect travel, rivers and low-lying areas.

Northern Zone: Localized thunderstorms could cause rapidly changing conditions.

Caribbean slope: Isolated downpours and lightning are possible despite the primary disturbance being located on the Pacific side.

Central Valley and highlands: Cloud cover, rain and mountain fog may reduce visibility on exposed roads.

Flooding and landslide concerns

Costa Rica’s rugged topography makes it particularly vulnerable when tropical moisture produces prolonged rainfall.

Steep slopes can become unstable, while rivers draining mountainous watersheds may rise quickly.

Residents should monitor the IMN and the National Emergency Commission (CNE), especially before traveling through mountainous areas or crossing rivers.

4. Panama: Significant Rainfall and Saturated Ground

Panama has also been dealing with unstable weather associated with the regional monsoon trough and nearby low-pressure systems.

On November 6, Panama’s National Civil Protection System (SINAPROC) reported that significant rainfall monitoring remained in effect through that Friday evening.

The agency explained that moisture entering from the Pacific was contributing to unstable weather, particularly in western and central Panama.

Its published forecast highlighted potential rainfall accumulations of 120–200 millimeters (4.7–7.9 inches) in several regions over the advisory period. This was a forecast associated with the November 6 notice, not a confirmed measured total or a newly verified November 7 forecast.

Areas highlighted in the advisory

• Chiriquí

• Veraguas

• Coclé

• Azuero Peninsula

• Ngäbe-Buglé comarca

Main concerns

Flooding in low-lying communities, rising streams, lightning, saturated slopes and transportation difficulties remain important hazards where further rain develops.

Western Panama is particularly sensitive to heavy rainfall because of its mountainous terrain and numerous rivers.

The November 6 prevention notice expired at 11:59 p.m. that day. Its extension into November 7 has not been verified here, so readers should check SINAPROC and Panama’s Institute of Meteorology and Hydrology (IMHPA) for the current warning status.

5. Honduras: Localized Flooding and Mountain Weather

Honduras lies north of the main Pacific disturbance, but changes in regional moisture circulation could still influence rainfall patterns.

The country’s mountainous interior, Pacific-facing southern districts and Caribbean watersheds can experience very different weather conditions on the same day.

Hazards to monitor

• Locally intense thunderstorms.

• Rapid river and stream rises following heavy rainfall.

• Landslides in mountainous communities.

• Lightning and reduced visibility.

• Potential road disruptions near steep slopes and river crossings.

There is insufficient verified evidence in the sources reviewed to declare a new nationwide flooding emergency in Honduras today.

The country’s Permanent Contingency Commission (COPECO) and national weather authorities should be consulted for current departmental warnings.

6. El Salvador: Thunderstorms and Flood-Prone Terrain

El Salvador’s Pacific-facing location makes the movement of the offshore disturbance relevant to its short-term weather outlook.

Although the most significant confirmed rainfall signal is farther south, changes in the disturbance’s position could alter the distribution of tropical moisture.

Main concerns

Pacific coastal districts: Monitor the possibility of heavy showers and thunderstorms.

Mountain communities: Rainfall over steep terrain may increase the risk of localized landslides.

Urban areas: Intense downpours can overwhelm drainage systems and produce short-duration flooding.

Road travel: Slippery surfaces, poor visibility and isolated falling debris can create hazardous conditions.

No new nationwide severe-weather emergency for El Salvador was independently confirmed in this report.

Readers should follow El Salvador’s Ministry of Environment and Natural Resources (MARN) and civil protection authorities for official alerts.

7. Guatemala: Cooler Highlands, Fog and Localized Rainfall

Guatemala is moving through its seasonal transition toward generally drier conditions, although rainfall can persist in parts of the country during November.

High-elevation communities may experience noticeably cooler mornings, while localized showers can still affect Pacific-facing slopes, northern districts and mountainous areas.

Weather hazards to monitor

Highland temperatures: Cooler overnight and early morning conditions may affect communities around Quetzaltenango and Huehuetenango.

Mountain fog: Reduced visibility can create dangerous driving conditions, particularly on winding highland roads.

Localized rainfall: Isolated heavy showers could still trigger flooding in vulnerable watersheds.

Landslides: Areas previously affected by heavy rainfall may remain susceptible to slope instability.

Seasonal outlook

Guatemala’s November weather can be influenced by cold fronts approaching from North America.

These systems sometimes produce cooler temperatures, stronger winds and increased rainfall along Caribbean-facing slopes.

However, no specific new cold-front warning for November 7 has been independently verified in the sources reviewed.

Residents should consult INSIVUMEH and CONRED for current weather forecasts, earthquake information and emergency advisories.

8. Belize: Caribbean Showers and Coastal Conditions

Belize remains outside the primary area of Pacific rainfall associated with the developing low-pressure system.

Nevertheless, changing Caribbean moisture and localized thunderstorms can still affect the country during November.

Main hazards to monitor

Coastal showers: Brief periods of heavy rainfall may affect communities along the Caribbean coast.

Localized flooding: Intense thunderstorms can overwhelm drainage in urban and low-lying areas.

Marine conditions: Boaters and fishermen should monitor changing winds, wave heights and thunderstorm activity.

Lightning: Isolated thunderstorms can pose hazards to outdoor activities.

No new nationwide severe-weather emergency for Belize was verified for this edition.

The National Meteorological Service of Belize remains the primary authority for district forecasts and coastal marine warnings.

9. Earthquake Activity: Monitoring Central America’s Active Fault Zones

Central America sits along one of the world’s most geologically active regions.

The interaction of the Cocos and Caribbean tectonic plates contributes to frequent earthquakes, particularly along the Pacific margin.

Countries including Guatemala, El Salvador, Nicaragua and Costa Rica experience regular seismic activity.

Main earthquake hazards

• Strong ground shaking near active faults and subduction zones.

• Landslides triggered by earthquakes in mountainous terrain.

• Structural damage from shallow earthquakes.

• Tsunami hazards following certain large offshore earthquakes.

Earthquake status for November 7

A complete, independently verified list of earthquakes occurring during the latest 24-hour period was not available for this edition.

Consequently, Orbis Weather is not reporting an unverified earthquake magnitude, location or casualty figure.

Readers can consult the USGS Latest Earthquakes Map for recent seismic observations.

Earthquake activity cannot be reliably predicted by date, location and magnitude. A region’s long-term seismic risk should not be interpreted as evidence that a major earthquake is imminent.

10. Volcano Activity: Guatemala, Nicaragua and Costa Rica

Central America’s volcanic chain stretches along the Pacific side of the region and contains numerous active and potentially active volcanoes.

Volcanic activity can include gas emissions, ash plumes, seismic unrest and, at some volcanoes, eruptive activity.

These are established volcanic hazard profiles, not confirmations of eruptions occurring today. No new November 7 eruption or volcanic emergency has been independently verified for this report.

Rainfall and volcanic hazards

Heavy rain can mobilize loose volcanic material, producing dangerous mudflows known as lahars.

These flows can move rapidly through river channels and valleys, even when a volcano is not undergoing a major eruption.

For current activity reports, consult the Smithsonian Global Volcanism Program and the appropriate national geological or volcanic monitoring agency.

11. Flooding and Landslides: Central America’s Most Immediate Threat

The most important natural hazard across parts of Central America this weekend is heavy rainfall associated with the eastern Pacific disturbance.

Flooding and landslides are especially concerning because they can occur without a tropical storm being officially named.

Why flooding can become dangerous quickly

Rainfall intensity: A short period of torrential rain can overwhelm drainage systems, especially in urban areas.

Saturated soil: When the ground becomes waterlogged, additional rainfall produces more surface runoff.

Mountainous terrain: Water can move rapidly downhill into narrow valleys, streams and populated areas.

Repeated thunderstorms: Several rain bands affecting the same watershed can produce significant cumulative rainfall.

Unstable slopes: Saturated hillsides can fail suddenly, sometimes blocking roads or damaging buildings.

Practical safety precautions

Residents and travelers in affected areas should avoid crossing flooded roads, rivers and drainage channels.

People living near steep slopes should remain alert for unusual ground movement, fresh cracks, falling rocks or sudden changes in stream flow.

Those in flood-prone communities should identify higher ground and follow evacuation instructions from local authorities.

12. Marine Conditions: Pacific and Caribbean Coasts

Central America’s Pacific and Caribbean coastlines can experience substantially different weather conditions.

Pacific coast

The developing low-pressure disturbance may contribute to unsettled marine weather, including thunderstorms, heavy rain and locally gusty winds.

Small vessels should exercise caution near active thunderstorms, particularly off Nicaragua and Costa Rica.

Caribbean coast

Marine conditions along Belize, Honduras, Nicaragua, Costa Rica and Panama depend on local wind patterns, showers and thunderstorms.

No specific region-wide wave-height forecast or marine warning has been independently confirmed for this edition.

Mariners should consult national marine forecasts and official coastal advisories before departure.

13. Central America Weather Outlook: November 7–10, 2026

This is a broad regional outlook based on the latest reviewed NHC guidance, not a verified daily forecast for every country. The timing and location of rainfall may change considerably.

14. Orbis Weather Risk Assessment

The following table provides a qualitative summary of hazards requiring attention. It is an editorial assessment, not an official government warning classification.

The strongest evidence for immediate rainfall concerns comes from the NHC’s Pacific disturbance outlook, Costa Rica’s November 7 national forecast and Panama’s November 6 rainfall notice.

15. Official Weather and Natural Hazard Sources

Orbis Weather uses recognized meteorological, geological and emergency-management agencies to inform its regional reporting.

16. Orbis Weather Analysis: Why This Weekend Matters

The developing Pacific disturbance illustrates a recurring challenge for Central America: a weather system does not need to become a hurricane or even a tropical storm to cause serious damage.

The region’s geography amplifies rainfall hazards.

Moist air moving inland from the Pacific can rise over steep mountains, producing intense rainfall. Water then flows into narrow valleys and densely populated communities, sometimes with little warning.

For Nicaragua and Costa Rica, the proximity of the offshore disturbance creates a particular concern about repeated rainfall.

For Panama, recent significant-rainfall advisories underline the importance of monitoring ground conditions and local drainage systems.

The key uncertainty is how the low-pressure system evolves and where its heaviest rain bands develop.

The NHC’s reduced formation probability should not be interpreted as an all-clear for flooding.

17. Final Outlook: Heavy Rain Remains the Main Concern

Central America enters Saturday, November 7, with an eastern Pacific disturbance capable of producing additional heavy rainfall even if it never becomes a named tropical storm.

Nicaragua and Costa Rica remain the principal countries to monitor, while Panama’s recent rainfall concerns warrant continued attention.

Elsewhere, localized thunderstorms, mountain fog, seismic activity and volcanic hazards remain part of the region’s broader natural hazard picture.

The main message from Orbis Weather: The most immediate threat is flooding and landslides, not necessarily tropical cyclone development.

Residents, travelers and emergency managers should follow official national forecasts, particularly where heavy rainfall affects mountainous terrain or flood-prone communities
