When I stopped by Duck Hollow on Monday 2 June the Monongahela River was so high that the mud bar was totally submerged. If killdeer nested there this spring, the flood ended their breeding season.

At first the high water was a mystery because it hadn’t rained hard in Pittsburgh but this water came from last week’s heavy rain in West Virginia. It took a while to come downstream.

Pittsburgh is getting its own taste of flooding this weekend. Yesterday isolated thunderstorms dropped more than an inch of rain in some areas and caused immediate flash floods.

Much of the destruction will be cleared away today but it won’t be permanent. Tomorrow, Sunday 8 June, 1.2 inches of rain are predicted in intense downpours at 9am and thunderstorms at 1pm.

The weather will be challenging for Phipps BioBlitz tomorrow.
