North America Weather Overview

North America faces a mixture of early-season winter storms, heavy rainfall threats, localized flooding, strong winds and changing tropical conditions on Tuesday, November 10, 2026.

The most significant weather concerns include dangerous winter travel in Alaska and northern Canada, increasing storm potential along the Pacific Northwest and northern California, and a developing lake-effect snow pattern around the Great Lakes.

Meanwhile, localized flood warnings remain in effect across several parts of the United States, although NOAA’s Weather Prediction Center does not identify a widespread excessive-rainfall risk for November 10–12.

In the tropics, the Atlantic Ocean, Caribbean Sea and Gulf of Mexico remain free of active tropical cyclones, while Tropical Storm Pena continues moving westward through the Central Pacific, southwest of Hawaii.

1. United States Weather Today

Pacific Northwest and California — Heavy Rain, Mountain Snow and Coastal Winds

An increasingly active Pacific weather pattern is expected to affect Washington, Oregon and northern California during the coming days.

NOAA’s extended forecast identifies elevated risks of heavy precipitation, high-elevation snowfall and strong coastal winds between November 10 and November 13.

Areas requiring particular attention include:

• Western Washington and Oregon, where repeated rainfall may create localized flooding concerns.

• The Cascade Mountains, where significant snowfall could affect mountain passes.

• Northern California and the Klamath Mountains, where heavy precipitation and mountain snow are possible.

• The northern Sierra Nevada, where winter travel conditions may deteriorate.

• Exposed Pacific coastal areas, where strong winds could affect transportation and marine activities.

These are forecast hazards rather than confirmation that every location is experiencing severe weather today.

Great Lakes and Northeast — Lake-Effect Snow Developing

A colder air mass is forecast to move southward from Canada toward the Great Lakes and northeastern United States later this week.

According to the Weather Prediction Center, lake-effect snow conditions could develop as cold air passes over the comparatively warm waters of Lakes Superior and Michigan.

The Upper Peninsula of Michigan is among the areas where several inches of snowfall may accumulate Thursday into early Friday.

Other locations downwind of the Great Lakes should monitor updated forecasts as the position and intensity of snow bands become clearer.

Lake-effect snow can produce substantial differences in snowfall over relatively short distances, creating difficult travel conditions even when nearby communities receive little accumulation.

Southern United States — Localized Flooding Remains a Concern

Although the national excessive-rainfall outlook is relatively quiet, existing river and flood warnings remain important.

An early-morning November 10 warning summary identified flood warnings affecting portions of:

• Florida, including parts of central Florida and DeSoto County.

• Texas, including several Hill Country and western Texas counties.

• Arizona, including Maricopa County.

• Iowa, including Benton and Iowa counties.

These are localized warnings, not evidence of a single widespread flooding event.

Residents should avoid driving through flooded roadways, monitor river levels and follow local emergency management instructions.

Alaska — Blizzard Conditions and Strong Winds

Alaska is experiencing some of North America’s more immediate winter-weather hazards.

A November 10 morning warning summary identified blizzard warnings around Thompson Pass and the Beaufort Sea coast, along with a high wind warning for the northern Denali Borough.

Potential impacts include severely reduced visibility, drifting snow, dangerous driving conditions and disruption to remote transportation routes.

Travelers should check current Alaska National Weather Service advisories before beginning journeys, particularly in exposed mountainous or coastal areas.

2. Canada Weather Today

Yukon and Northern British Columbia — Dangerous Winter Travel

Winter weather is creating hazardous conditions across portions of northern Canada.

Warnings issued November 9 highlighted snow, blowing snow and possible near-zero visibility along sections of Haines Road between Haines Junction and Pleasant Camp.

The Dempster Highway near the Richardson Mountains has also faced blizzard conditions.

These hazards are especially serious along remote highways, where emergency services and fuel stops may be separated by considerable distances.

Motorists should carry winter survival equipment, check road closures and avoid unnecessary travel during blizzard conditions.

Alberta and the Canadian Rockies

Mountain roads in western Canada remain vulnerable to snow, ice and rapidly changing visibility.

Drivers using high-elevation routes should prepare for winter conditions even when lower-elevation communities experience comparatively mild weather.

Ontario, Quebec and Atlantic Canada

The developing cold-weather pattern over the Great Lakes may influence southern Ontario and neighboring regions as the week progresses.

Forecast details, precipitation type and any active warnings should be checked locally rather than assuming that the entire region will experience the same conditions.

Environment and Climate Change Canada provides province-by-province forecasts and active warning information.

3. Mexico Weather and Natural Hazards

Mexico’s weather hazards vary considerably between its northern deserts, central highlands, Pacific coast and tropical southeastern regions.

Northern Mexico

Cold fronts moving southward from the United States can bring falling temperatures, gusty winds and localized precipitation to northern Mexican states.

Mountainous areas may experience colder conditions than surrounding lowlands.

Central Mexico

Residents of elevated cities and mountainous communities should remain aware of cool overnight temperatures, localized fog and changing visibility.

Southern Mexico and the Pacific Coast

Heavy showers, thunderstorms and localized flooding remain important seasonal hazards in southern Mexico.

Mountain communities are particularly vulnerable to landslides when prolonged rainfall saturates steep terrain.

Verification note: A current, nationwide Mexican warning bulletin was not independently confirmed for this edition. These descriptions identify regional weather vulnerabilities and should not be interpreted as active November 10 alerts.

For official warnings, consult Mexico’s Servicio Meteorológico Nacional.

4. Atlantic, Caribbean and Gulf of Mexico Tropical Outlook

The National Hurricane Center reports no active tropical cyclones in the Atlantic basin as of its November 10 morning update.

This includes the Atlantic Ocean, Caribbean Sea and Gulf of Mexico.

However, the Atlantic hurricane season continues officially through November 30, meaning tropical development remains possible during the final weeks of the season.

Marine interests should continue monitoring offshore weather systems, strong winds, rough seas and any new tropical disturbances.

5. Eastern and Central Pacific Tropical Weather

Eastern Pacific

The National Hurricane Center reported no active tropical cyclones in the Eastern North Pacific east of 140°W in its November 10 morning update.

Central Pacific — Tropical Storm Pena

NHC ADVISORY | NOVEMBER 10, 5:00 AM HST

Tropical Storm Pena is moving westward southwest of the main Hawaiian Islands.

The storm’s center is well south of Hawaii, and its latest forecast track, marine impacts and any changes in intensity should be monitored through the Central Pacific Hurricane Center.

Its presence does not mean that hurricane conditions are occurring across the Hawaiian Islands.

6. Wildfires and Smoke Across North America

Wildfire activity remains a year-round concern in some parts of North America, although seasonal risk varies substantially.

Western United States

Dry vegetation, low humidity and strong winds can increase the potential for rapid wildfire spread, particularly in areas experiencing prolonged dry conditions.

In northern California, a prescribed fire operation was reported on the San Juan Ridge on November 10, involving approximately 140 acres of planned treatment.

Prescribed burning is a controlled land-management activity and should not be confused with an uncontrolled wildfire.

Canada

Although peak wildfire season has passed in many Canadian regions, active incidents and smoke conditions should still be checked using provincial fire services and air-quality monitoring networks.

Air Quality and Smoke Exposure

Smoke can travel considerable distances from its source, affecting communities that are not directly threatened by flames.

People with respiratory or cardiovascular conditions, children and older adults may be particularly sensitive to elevated particulate pollution.

Current-data limitation: No verified continent-wide November 10 wildfire incident count or live AQI dataset was available for this report. Orbis Weather is therefore not assigning specific air-quality categories or claiming new uncontrolled fires without confirmation.

7. Earthquakes and Seismic Activity

North America contains several major seismic zones, including Alaska, the Pacific Coast, Mexico and parts of the Caribbean.

Alaska and the Aleutian Islands

The interaction of the Pacific and North American tectonic plates makes southern Alaska and the Aleutian Islands among the continent’s most seismically active regions.

California and the Western United States

California’s San Andreas Fault system and surrounding faults remain important sources of earthquake risk.

Mexico

Southern and western Mexico experience frequent seismic activity associated with the subduction of oceanic tectonic plates beneath the North American region.

Pacific Northwest

The Cascadia Subduction Zone is capable of producing powerful earthquakes and tsunamis, although such events cannot currently be predicted to an exact date or time.

Earthquake verification: This report does not present an unverified list of November 10 earthquakes. For event magnitudes, depths, locations and origin times, readers should consult the USGS real-time earthquake catalog.

8. Volcano Monitoring

Volcanic activity is monitored continuously across several North American regions.

Volcanic ash can disrupt aviation, damage machinery and reduce visibility. Sulfur dioxide and other volcanic gases can also affect air quality near active volcanoes.

This table describes monitoring priorities, not confirmed eruptions today. No specific November 10 eruption status has been independently verified for inclusion.

9. Flooding, Landslides and Coastal Hazards

Flooding

Flood hazards vary from long-duration river flooding to sudden flash flooding caused by intense thunderstorms.

Even when national forecasts show a low risk of widespread excessive rainfall, localized flooding can persist in river basins and poorly drained areas.

NOAA’s November 10 outlook indicates no designated excessive-rainfall risk area for November 10–12, while identifying a marginal risk for parts of central and southern Texas later in the week.

Landslides

Steep terrain in the Pacific Northwest, California, British Columbia and mountainous Mexico can become unstable during prolonged or intense rainfall.

Burn scars left by previous wildfires can be especially vulnerable to rapid runoff and debris flows.

Coastal Hazards

Residents and marine operators should remain alert to high surf, rip currents, coastal flooding and strong offshore winds.

These conditions may develop independently of named tropical storms.

10. Greenland and the Arctic Region

Greenland and the wider North American Arctic face hazards associated with snowstorms, extreme cold, strong winds and sea ice.

In coastal communities, rapidly changing weather can disrupt aviation, marine transportation and essential supplies.

Long-term changes in Arctic temperatures, glaciers and sea ice also influence coastal ecosystems and transportation conditions.

No specific Greenland-wide severe-weather warning has been independently verified for November 10 in this report.

11. North America Weather Outlook — November 11–13

These are regional forecast concerns, not a guarantee that every listed location will experience hazardous conditions.

12. North America Natural Hazards Summary

13. Weather Safety and Preparedness

15. Orbis Weather Editorial Methodology and Transparency

How this report is prepared

This North America Weather & Natural Hazards Today report is independently written and edited for Orbis Weather by Paul Harrison.

The report combines available official weather bulletins, meteorological forecasts, natural hazard monitoring information and relevant regional reporting.

Our editorial approach distinguishes between three types of information:

Observed conditions: Weather events, warnings or natural hazards confirmed through available official or credible reporting.

Forecast conditions: Expected developments based on meteorological guidance. Forecasts are inherently uncertain and may change as new observations become available.

Background risk: General geographic or seasonal hazards included to help readers understand regional vulnerabilities. These are not presented as confirmed active incidents.

Where current observations or warning information cannot be independently verified, that limitation is identified rather than replaced with estimates or assumptions.

Important Limitations

North America covers a vast geographical area, and conditions may differ significantly between neighboring communities.

This article is a regional overview, not a comprehensive inventory of every active weather warning, earthquake, wildfire or natural hazard.

Some official alerts may be issued, revised or canceled after publication. Regional sections without verified live data should not be interpreted as all-clear notices.

Corrections and Updates

Orbis Weather aims to provide accurate, clearly sourced weather reporting. When material factual errors are identified, corrections should be made promptly and significant updates clearly dated.

Readers should consult the latest official advisories for decisions involving travel, evacuation, marine safety or emergency preparedness.

16. Final Outlook — North America Today

North America’s weather pattern on November 10, 2026, highlights the transition toward winter across northern latitudes while the Pacific storm season becomes increasingly active.

The most immediate concerns include blizzard conditions in Alaska and northern Canada, localized U.S. flooding, and developing heavy precipitation and mountain snowfall threats along the western United States.

The Great Lakes region is also preparing for colder conditions and possible lake-effect snowfall later this week.

In the tropics, the Atlantic basin remains free of active cyclones, while Tropical Storm Pena continues moving westward across the Central Pacific.

The overall message is one of regional contrasts: dangerous winter conditions in the far north, developing Pacific storms in the west and localized hazards elsewhere.

Orbis Weather will continue following significant weather developments, tropical systems, earthquakes, wildfires and other natural hazards affecting North America.
