ABOVE 111 DEGREES, IT SHOULD BE BRIEF AND THUS SPECIAL WEATHER

(LEVEL 3 OF 4) TO EXTREME (LEVEL 4 OF 4) HEAT RISK WILL CONTINUE
IN NEXT WEEK.
WHILE RAIN CHANCES WILL CONTINUE INTO NEXT WEEK, CHANCES HAVE
TRENDED DOWNWARD SLIGHTLY WITH A 10-25% CHANCE MOST DAYS,
ESPECIALLY ALONG THE SEA BREEZE. BEST CHANCE OF RAIN WILL BE ON
WEDNESDAY WITH CHANCES UP TO AROUND 30%. ANY CONVECTION THAT DOES
DEVELOP COULD PRODUCE LOCALLY HEAVY RAIN, GUSTY WINDS, AND CLOUD
TO GROUND LIGHTING.
WHILE THERE IS A LOW RISK OF RIP CURRENTS AT AREA BEACHES THIS
