Main impact from #Ida as it moves through will be heavy rainfall, flash flooding and river flooding. Forecast rainfall amounts from local NWS offices.

The forecast rainfall from #Ida pushes a number of local creeks and rivers into the moderate flooding category. Here is the Schuylkill River at Norristown.

Here is Perkiomen Creek at Graterford, PA.

Here is Brandywine Creek at Chadds Ford, PA.

And the Raritan River at Bound Brook, NJ.
Again, all these graphs are based on forecast rainfall. They will be updated as the rainfall arrives and actual reports come in. Be prepared for changes. Monitor the forecasts during the day Wednesday.
