Los Angeles, US West Brace for Second Bout of Record March Heat

Los Angeles and the US Southwest are set for a second record heat wave in two weeks as temperatures soar, potentially straining electric grids, melting snowpack and raising health risks.

Tuesday’s high in downtown Los Angeles is forecast to reach 97F (36C), possibly climbing to 98F by Thursday, according to the National Weather Service. Commercial forecaster AccuWeather Inc. said temperatures may rise as high as 99F, which would tie March 29, 1879, for the warmest March reading on record.
