Red Flag Warnings are in effect across the Central Plains and Southeast United States on March 28, 2026, as the National Weather Service (NWS) warns of critical fire weather conditions driven by strong winds, low relative humidity, and dry fuels. Wind gusts up to 80 km/h (50 mph) and humidity levels as low as 10–20% are expected to promote rapid fire ignition and spread. Outdoor burning is strongly discouraged across all warned regions.
Airborne snow surveys in the Upper Black River Basin of eastern Arizona showed snow water equivalent falling from about 11.7 million m3 (9.5 thousand acre-feet) on February 23 to about 987 000 m3 (0.8 thousand acre-feet) by March 12, 2026, a decline of more than 90% in less than three weeks. The basin feeds the Salt River system upstream of Roosevelt Dam, part of the reservoir network supplying water to more than 2.5 million people in the Phoenix metropolitan area.
