THE NATIONAL WEATHER SERVICE HAS RECEIVED A REPORT OF FUNNEL CLOUDS

WEAK THUNDERSTORMS. THESE FUNNELS ARE NORMALLY BRIEF…DROP ONLY
A FEW HUNDRED FEET FROM THE CLOUD BASE…AND RARELY BECOME A
TORNADO OR CAUSE DAMAGE. HOWEVER…IF ONE IS SPOTTED…PLEASE
REPORT IT IMMEDIATELY TO LOCAL LAW ENFORCEMENT FOR RELAY TO THE
NATIONAL WEATHER SERVICE. IF A TORNADO WARNING WOULD BECOME
NECESSARY…TAKE APPROPRIATE ACTION.
