EDT...

AT 620 PM EDT...NATIONAL WEATHER SERVICE DOPPLER RADAR INDICATED A 
CLUSTER OF THUNDERSTORMS PRODUCING VERY HEAVY RAINFALL JUST TO THE 
NORTH AND EAST OF THE CITY OF JOHNSTOWN...MOVING NORTHEAST AT 10 
MPH. 

THE RAINS HAVE TAPERED OFF TO A LIGHTER INTENSITY OVER THE CITY OF 
JOHNSTOWN ITSELF. THESE SLOW MOVING THUNDERSTORMS HAVE ALREADY 
PRODUCED TORRENTIAL RAINFALL IN THE JOHNSTOWN METRO AREA...AND HAVE 
MOVED TO THE NORTH AND EAST.  

EXCESSIVE RUNOFF FROM THIS STORM WILL CAUSE FLASH FLOODING OF SMALL 
CREEKS AND STREAMS...HIGHWAYS...STREETS AND UNDERPASSES. MANY ROADS 
HAD BEEN CLOSED IN THE JOHNSTOWN METRO AREA DUE TO HIGH WATER. 
LOCAL EMERGENCY MANAGEMENT OFFICIALS REPORT THAT THE WATER HAS BEGUN 
TO RECEDE A BIT IN THE PLACES THAT WERE HIT THE HARDEST.  

HOWEVER...SMALL CREEKS AND STREAMS OUTSIDE OF JOHNSTOWN...ESPECIALLY 
TO THE NORTH AND EAST...INCLUDING PLACES NEAR EBENSBURG...SOUTH FORK 
AND DUNLO...COULD STILL RAPIDLY FLOOD...POSSIBLY WASHING OUT ROADS 
AND FLOODING NEARBY LOW AREAS.

DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE WATER COVERS THE
ROADWAY. VEHICLES CAUGHT IN RISING WATER SHOULD BE ABANDONED. MOVE TO
HIGHER GROUND TO ESCAPE FLOOD WATERS.
