Warnings and Notices

	Areal Flood Advisory
Statement as of 12:57 PM EDT on July 11, 2009 The National Weather Service in State College PA has issued an * urban and small stream flood advisory for... northwestern McKean County... Warren County... * until 400 PM EDT... * at 1254 PM EDT Doppler radar indicated heavy rain was falling due to a line of slow moving... training thunderstorms that extended from Bradford... to Warren and Grand Valley. Doppler radar estimates that between 1 and 1.25 inches of rain has fallen in the last hour. Additional rainfall of up to one inch is possible in the advisory area between 1 and 230 PM. Expect minor flooding to begin shortly. * Locations in the advisory include but are not limited to Bradford... Eldred... Kane... Lewis Run... Clarendon... Tidioute and Warren. Precautionary/preparedness actions... A flood advisory means that although streams and creeks may be elevated or even rise out of their banks... property damage will be minimal. Inconveniences can be expected but the flooding will not be immediately life threatening. In hilly terrain there are hundreds of low water crossings which are potentially dangerous in heavy rain. Do not attempt to travel across flooded roads. Find alternate routes. It takes only a few inches of swiftly flowing water to carry vehicles away. Be prepared to take action if the flooding threat increases... or a Flash Flood Warning is issued. Lat... Lon 4199 7824 4163 7883 4163 7962 4187 7959 4201 7901 Forecaster: Lambert
