Unprecedented March Heat Wave Strikes U.S. West

San Francisco and several Western cities are experiencing record-breaking March temperatures during an unusual heat wave affecting much of the U.S. West. Cities accustomed to cooler weather, like San Francisco, have nearly hit 90 degrees, while others like Phoenix and Las Vegas anticipate unprecedented heat for the month.

San Francisco residents revealed more skin than usual for this time of year as a rare winter heat wave struck the U.S. West. The city, known for its chilly summers, experienced nearly 90-degree temperatures in March for the first time in two decades.

In Phoenix, temperatures are expected to exceed 100 degrees this week, marking the earliest time they've reached such heights, while Las Vegas might set new March temperature records. Meanwhile, severe snowstorms led to travel disruptions in the Midwest and eastern U.S.

Meteorologists urge visitors to Southwest cities and national parks to prepare for extreme conditions, while water providers in Colorado are advocating for conservation amid unusually warm winter weather affecting snowfall and water supplies.
