significant across much of northern Erie County from Fairview and 
Lake City east to the Erie area. Radar estimated between 4 and 5 
inches of rain fell from early this afternoon through early evening. 

Numerous roads were reported closed by flood waters. An estimated 
100 homes, just in the Millcreek Township area, were damaged by 
flood water or had water in the basements. One home in Millcreek 
township that was on a bluff, collapsed due to flowing water. 

In addition, water rescues were needed in Fairview, Lake City, and 
Mill Village, when motorists became stranded. In one case flood 
waters were up to the car's windows.

Debris from flooding was also reported across the road in the 
vicinity of west 12th street and Greengarden Blvd on the southwest 
side of Erie.

Additional flooding is likely.  Some locations that may experience 
flooding include... Erie, North East, Northwest Harborcreek, 
Harborcreek, Lawrence Park, Wesleyville, McKean and Middleboro.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

Excessive runoff from heavy rainfall will cause flooding of small
creeks and streams, urban areas, highways, streets and underpasses as
well as other drainage areas and low lying spots.
