The biggest stories

Record river crests in the US Southwest

Two days of heavy rain sent rivers in Arizona, Colorado and New Mexico to all-time highs. The Weather Channel reported on 3 November that 15 river gauges set record crests on 1 November, after 127 to 178 mm (5 to 7 in) of rain in a day. Workman Creek, Arizona, recorded 185 mm (7.3 in) in two days, and Flagstaff 131 mm (5.15 in), its wettest 1 November on record, AP reported on 3 November.

AP confirmed one death, a 73-year-old man in Flagstaff; a second death is suspected to be weather-related. Dozens were rescued and hundreds evacuated, including in Pagosa Springs, Colorado, and Chama, New Mexico. The San Juan River at Pagosa Springs reached 5.12 m (16.81 ft) on 1 November, about 0.3 m (1 ft) below its 1911 record. Arizona declared a statewide emergency; New Mexico and Colorado have requested major disaster declarations.

Florida’s extreme rainfall

Southern Brevard County received up to 610 mm (24 in) of rain on 1 and 2 November, The Weather Channel reported. Melbourne’s 292 mm (11.51 in) on 2 November was its wettest day in 89 years. Infobae reported on 3 November that rainfall in parts of Brevard exceeded a 1-in-1,000-year threshold.

ABC News reported two deaths and hundreds of rescues on 3 November, including more than 60 by state wildlife officers in Brevard. A state of emergency covers seven counties, and 30 polling precincts were moved, Infobae reported. The Weather Prediction Center warned of further flash flooding on the southeast coast on 4 November.

Two cyclones hit Andhra Pradesh in six days

Severe Cyclonic Storm Arnab made landfall around 08:00 local time on 28 October near Visakhapatnam with winds of 110 to 120 km/h (68 to 75 mph), Down To Earth reported. About 58,000 people were evacuated to 1,000 camps and crops on about 70,900 hectares were hit. Death tolls conflict: Al Jazeera cited the national disaster force’s figure of at least 3, while Ratopati reported 7.

Severe Cyclonic Storm Murasu followed, making landfall near Ongole early on 3 November with winds of 100 to 110 km/h (62 to 68 mph), according to Dainik Jagran English. Kothapatnam recorded 164 mm (6.46 in) of rain. TheNewsMinute reported on 4 November that two people died in Bapatla district and preliminary losses were about Rs 344 crore. By 05:30 IST on 4 November, the India Meteorological Department had downgraded Murasu to a depression over Telangana, with heavy rain still forecast.

Deadly flash floods in northeast Syria

Flash floods on 28 and 29 October struck Raqqa, Deir ez-Zor and Hasakah. The state news agency SANA reported on 30 October that at least five people died, including four children, with five missing. Reuters later the same day cited a minister putting the toll at seven dead and four missing.

About 375 families were evacuated from three displacement camps, SANA said. Al Jazeera reported that the al-Salmani Bridge west of Tabqa collapsed, cutting the Raqqa–Aleppo road.

Storm Agneta floods Greek islands

Agneta, the first officially named Mediterranean storm of the autumn, brought flooding to Greece and gusty winds to southern Italy from 1 to 3 November. Thasos recorded 144 mm (5.67 in) on 1 November, according to meteo.gr data cited by Euronews. On Rhodes, a river overflowed at Archangelos and more than 60 vehicles were swept away, tempo.pt reported on 3 November.

Greek Civil Protection placed seven regions on red alert for 2 and 3 November. In Italy, the bora gusted to 109 km/h (68 mph) in Trieste, La Voce d’Italia reported. No deaths were reported.

Climate context

A strong El Niño is under way and still strengthening. NOAA’s Climate Prediction Center kept an El Niño Advisory in its 8 October discussion, with a Niño-3.4 anomaly of +2.1°C (+3.8°F) and a strong-to-very strong event likely through January–March 2027; its next update is due 12 November. Australia’s Bureau of Meteorology reported on 27 October a record weekly relative Niño3.4 value of +2.88°C (+5.18°F), in a dataset starting in 2008. Sources linked Somalia’s floods, Ecuador’s rains and Bolivia’s drought emergency to El Niño. The Weather Channel attributed the US Southwest and Florida floods to an atmospheric river and a stalled low, not El Niño, and AFP noted it is difficult to attribute any single event to El Niño.

The week ahead

Typhoon In-fa near Japan’s Ogasawara Islands is the main storm to watch; no other tropical cyclone is active worldwide.

  • Typhoon In-fa, western North Pacific: JTWC gave 130 km/h (81 mph) sustained winds at 00:00 UTC on 3 November, about 280 km (150 nautical miles) southwest of Iwo To. PAGASA’s 04:00 local bulletin on 4 November gave 130 km/h (81 mph) with gusts to 170 km/h (106 mph). Forecasts cited by Weathernews take it northeast near Chichijima and Hahajima on 5 November, with high waves for about a week.
  • Central and eastern Pacific: NHC gave a disturbance (Invest 95E) well southeast of Hawaii a 70% chance of becoming a cyclone within seven days. A trough off Central America has a 30% chance and could bring heavy rain there late this week and over the weekend (NHC, 16:00 PST, 3 November).
  • Atlantic south of Bermuda: a low is expected to form on a weakening front and may become partly subtropical while drifting east. NHC gave it a 40% chance of formation within seven days (01:00 EST, 4 November).
  • United States: the Weather Prediction Center (03:00 EST, 4 November) expects storms with isolated heavy rain and severe weather from the lower Ohio Valley to the Southeast, more flash flooding on Florida’s southeast coast, and increasing snow on central Rockies peaks.
  • Somalia: UN and Somali agencies project more than 874,000 people could be displaced by flooding between October and December, FTL Somalia reported on 1 November.
