Severe Thunderstorms, Flash Flooding Possible
● By Anonymous
The National Weather Service issued a Severe Thunderstorm Warning and another Flash Flood Warning for Monday. At 9:57am the NWS doppler radar indicated severe thunderstorm capable of producing damaging winds up to 60mph. At the same time, excessive runoff from heavy rainfall will cause glooding of small creeks and streams, urban areas, highways, streets and underpasses as well as other drainage areas and low lying spots. Do not drive your vehicle into areas where the water covers the roadway. The water depth may be too great to allow your car to cross safely. Move to higher ground.
According to the National Weather Service, an area of low pressure will form along a stalled frontal boundary and head northeast from Eastern Pennsylvania into Southern New England. Heavy showers and thunderstorms will become increasingly likely as the low pressure moves over the area.
Rainfall rates of 1 to 2 inches per hour are possible with these showers and thunderstorms. Additionally, training of these showers and thunderstorms over the same area will be likely, leading to an increased potential for flash flooding.
The Severe Thunderstorm Warning expires at 10:30 am, while the Flash Flood Warning goes until 11:30am. The Flash Flood Watch continues through 10pm Monday.
