Flash flooding will continue to be a concern the next few days.
A stagnant weather pattern will help to fuel more showers and storms, with damaging winds and heavy rain the main threats.
Showers are possible for the morning and afternoon commutes Wednesday. Watch 11 Morning News starting at 4:30 a.m. for the latest timing on showers moving through the region.
Small creeks and streams could rise quickly, and landslides are also a concern.
Be alert for rapidly changing road conditions with any storm that moves through your area.

UPDATE 11:32 a.m. The Mon Wharf will be closed starting on Wednesday until further notice as a precaution.
Scattered thunderstorms will develop again Tuesday, with the strongest storms bringing the threat of damaging winds, localized flooding, hail and frequent lightning.
A flash flood watch has been issued for much of the area starting at 1 p.m. and lasting through the evening. A flash flood watch means conditions are favorable for flash flooding but not a certainty.
Thunderstorms will not be as widespread as Monday, but any storm that does develop will have the potential to become severe.
Many areas have been soaked with rain the past few days, and any additional heavy rain could cause flash flooding. Watch for quickly changing road conditions if storms develop.
The strongest storms will bring winds in excess of 50 mph and hail.
Severe storms possible later today. Damaging winds MOST likely east of the city of Pittsburgh, but strong storms possible anywhere today. pic.twitter.com/H4n9xmLDM9— Scott Harbaugh (@WPXIScott) May 15, 2018
