The East Coast has earthquakes and Hurricane Irene to worry about — while we have excessive heat through the weekend with the possibility of thunderstorms that could ignite brush, followed by flooding.   Nobody’s telling when the rain of frogs will occur.  National Weather Service shouts:

DAYTIME HIGH TEMPERATURES WILL CONTINUE TO EXCEED 100 DEGREES OVER MANY VALLEY AND LOWER MOUNTAIN LOCATIONS AS A DOMINANT HIGH PRESSURE SYSTEM REMAINS OVER THE SOUTHWESTERN UNITED STATES. SUNDAY HAS THE POTENTIAL TO BE THE HOTTEST AS THE RIDGE PEAKS IN INTENSITY.

A SOUTHERLY FLOW ALOFT WILL MOISTEN THE AIR MASS TODAY AND INCREASE HUMIDITIES OVER THE AREA. THIS WILL COMBINE WITH THE HOT AMBIENT  TEMPERATURES TO CREATE MORE HUMID CONDITIONS AND POSSIBLY PRODUCE POTENTIALLY DANGEROUS HEAT INDEX VALUES. HEAT INDEX IS A MEASURE OF HOW HOT IT REALLY FEELS. THE HIGHEST HEAT INDEX VALUES ARE  EXPECTED OVER THE LOS ANGELES COUNTY VALLEYS AND MOUNTAINS… WHERE VALUES BETWEEN 100 AND 107 ARE POSSIBLE. SUCH HIGH HEAT INDEX  VALUES MAKE IT DIFFICULT TO REMAIN COOL… AND POSES A POTENTIALLY FATAL RISK FOR HEAT ILLNESS AND FATIGUE…ESPECIALLY FOR THE HOMELESS…ELDERLY…AND PEOPLE WORKING OUTDOORS.
