PITTSBURGH (Newsradio 1020 KDKA) - The National Weather Service has issued a Flash Flood Watch from 1 p.m. through midnight in southwest Pennsylvania.

Between 1.5 and 2.5 inches of rain could fall and higher amounts are possible. Flash flooding of small streams and roads may result and landslides are also a concern.

AccuWeather's Elliot Abrams tells the KDKA Radio Morning News, besides today's thunderstorms and heavy rains, there will probably be showers each day the rest of the week. "It's a very, very wet pattern and that's a concern because, as the ground becomes more saturated and streams rise, it's easier to get flash flooding with each successive round of thunderstorms."

Allegheny County and areas to the south are expected to get the most precipitation. Areas to the north of Pittsburgh are less saturated and less prone to flash flooding. 

After a line of thunderstorms passes through the area today, a front is forecast to approach the region and stall. A couple of low pressure areas are expected to move along the front, each producing a wave of showers and thunderstorms. Abrams says: "It's going to be one of the wetter periods. It's not going to rain all the time but it could rain any time the rest of the week."

The Pittsburgh Public Parking Authority of Pittsburgh says it is closing the Mon Warf Wednesday at precaution due to the potential for flooding in the area. It adds the Warf will be closed until further notice.
