Severe floods affecting Gila County and parts of central Arizona since September 25, 2025, left at least four people dead and created a major hazmat risk in Globe after around 1 000 propane tanks were washed into the downtown area.

A series of atmospheric rivers (AR) is forecast to hit the U.S. West Coast from late September through early October, beginning with a strong AR that made landfall over British Columbia on September 26, 2025.

A large sea surface temperature anomaly has developed in the North Pacific Ocean, extending toward the U.S. West Coast.

At least 14 people were killed and 46 remain missing after the Maitai’an Creek barrier lake overflowed in Hualien County, Taiwan, on September 23, 2025.
