PITTSBURGH (KDKA) -- The severe weather risk for Tuesday has increased. 

Severe weather is expected across most of western Pennsylvania with more numerous storms for Beaver, Washington, Greene and western parts of Allegheny County, which is under an enhanced risk (3 out of 5). That means there's the possibility for isolated tornadoes, damaging winds over 60 mph and hail 1 to 2 inches in diameter. 

Storms will weaken as they move east towards Butler, Armstrong, Westmoreland and Fayette counties, but everyone is at risk for frequent lightning, hail and strong winds.

As for Monday, there's a flood warning for Greene and Fayette counties until 4 p.m. There's a flood watch that goes until 8 p.m. for Allegheny, Washington, Westmoreland, Greene, Fayette, Somerset and Garrett County, Maryland, and most of West Virginia until 8 p.m. Tuesday. 

Areas south of I-70 could pick up 2 to 5 inches of rainfall where flooding is already occurring. 

There's a flood advisory for the Ohio River at Pittsburgh through Thursday morning, where the river is expected to reach 18.5 feet by Wednesday afternoon, which means Mon Wharf will most likely close due to flooding and water will overflow on the North Shore riverwalk.
