A powerful heat wave has swept across the Southwest United States, with some areas reaching temperatures over 110 degrees Fahrenheit - about 30 degrees hotter than usual for this time of year. A small community near Martinez Lake, Arizona, set a new record for the hottest March temperature ever recorded in the U.S., only to be surpassed the following day by parts of California and Arizona hitting 112 degrees.

Why it matters

This extreme heat wave in March is highly unusual and concerning, as it is typically not seen until late May in the region. Meteorologists attribute the abnormal temperatures to a high-pressure system building over the area, creating a 'heat dome' that is expected to linger for some time.

The details

The record-breaking heat has already caused significant disruption, with schools and businesses forced to close due to the dangerous conditions. Residents are being urged to take precautions against heat-related illnesses and to limit time outdoors as much as possible.

• Last week, a small community near Martinez Lake, Arizona, hit 110 degrees, the hottest March temperature ever recorded in the U.S.
• The following day, areas of California and Arizona reached 112 degrees.

What’s next

Meteorologists are closely monitoring the high-pressure system and expect the extreme heat to continue for the foreseeable future, raising concerns about the impact on public health and the environment.
