Overview
- The National Weather Service reported Phoenix reached 93 degrees on March 2, breaking the 2016 daily record of 90.
- Monday marked the fourth consecutive day of tying or breaking record highs, and the city set a record warm low of 64 degrees for the date.
- Scottsdale Fire and other first responders reported increased heat-rescue calls, with officials urging hydration and shade during outdoor events.
- Forecasts call for highs in the mid-80s Tuesday and Wednesday, falling into the 70s by Friday, with breezy conditions and limited precipitation chances in the Valley.
- The record heat followed Phoenix’s warmest winter on record, which experts link to La Niña layered on long-term warming, and the West’s low snowpack is raising Colorado River concerns including a projection for roughly half-normal Lake Powell inflows.
