Allegheny County says Brandt School Road in Franklin Park is closed between Wexford Bayne Road and Corporate Drive due to flooding.

They also issued an alert for Penn Hills, saying asphalt from a bridge in the 4300 block Verona Road is washing away with floodwater.

Bethel Park is also affected by flooding. Bethel Park Police say Route 88 at Valley Drive is experiencing “flooding conditions.”

Other Bethel Park-area roads are experiencing some flooding as well. Police remind motorists to use caution and avoid flooded roads.

Moon Township Police Department says it’s a good idea to avoid University Boulevard southbound uphill from Stoops Ferry Road. They say there is flooding there too and they report it looks like another landslide could be imminent.

In addition, there were down power lines on Boggs School Road. Moon Township Police say Spring Run Road Ext. is closed from Boggs School Road to the Bon Meade Plan.

The 9000 block of Maple Street in Plum is also experiencing flooding.

Homes in North Fayette Township on Santiago Road are dealing with floodwaters. 911 dispatchers say multiple homes are flooded.

Due to the heavy rain, there’s also a mudslide on Scott Farm at Oakdale Road. Allegheny County says fire units are on the scene.

NWS has issued a severe thunderstorm warning for parts of Indiana County until 5:15 p.m.

They say the areas included in the warning are Indiana, Clymer and Rossiter.

Some areas that aren’t under warnings or watches are also experiencing flooding.

KDKA Meteorologist Ray Petelin says a nasty system is passing through the area this Halloween evening.

Gusty winds, potentially strong storms and rapidly falling temperatures can be expected over the coming hours.

Ray Petelin says it will be cold enough, by midnight, for the wind chills to feel like it is in the 20s. This will remain the case at the bus stop in the morning.

With the actual temperatures falling into the 30s overnight, any leftover rain could mix with — then change — to snow. Ray Petelin doesn’t expect there to be any accumulations.

High pressure will build into the region Friday. This will lead to gradually clearing skies.

Other than some late, isolated sprinkles Saturday, the weekend looks to stay dry and very cool.

A Tornado Watch was issued for much of central Pennsylvania, including the local counties of Armstrong, Cambria, Clairon, Fayette, Indiana, Jefferson, Somerset and Westmoreland, as well as Monongalia and Preston counties in West Virginia and Garrett County, Maryland.

The watch, however, was canceled.

KDKA viewer David DiGiacomo shared photos of a rainbow from his home on Elm Street in Butler. Hopefully there’s a rainbow at the end of all this Western Pennsylvania flooding.
