Many streams, creeks and rivers will also flood. The Schuylkill in Philly is forecast to crest just shy of Moderate Flood Stage Thursday afternoon. At this level, Route 1 off ramp to Ridge Avenue is flooded and closed. MLK Drive is flooded and closed between Greenland Drive and Montgomery Drive, and Main Street in Manayunk floods around Shurs Lane. Soil moisture conditions across portions of the area are in the 90%+ percentile range due to recent heavy rains and thus this will exacerbate the already high potential for flooding during this event. Widespread 2-5″+ of rainfall is expected across PA. Extremely excessive totals over 6″ are possible in the Poconos and Lehigh Valley. NJ and most of DE look to be in the 1-3″ rainfall range, with locally higher amounts. Rain looks to overspread the area, mainly N & W, overnight. Steady and periods of heavy rain is likely to persist through the duration of the event in the Poconos, Lehigh Valley, and Berks Co. In Philly proper, South Jersey and much of DE, the steady rain may not get going until late Thursday. Steady and heavy to torrential rain will affect the entire area tomorrow night. The good news is the latest runs of both the Euro and GFS have Ida out of here much more quickly, possibly as early as 6 a.m. Thursday. Pennsylvania Gov. Tom Wolf signed an emergency proclamation Tuesday ahead of Ida’s potential flooding.“This dangerous storm continues to have devastating impacts across the South and as it heads toward Pennsylvania, we are expecting significant rainfall across the state. This proclamation will allow for our emergency preparedness teams to provide any support needed throughout the storm and its aftermath,” Gov. Wolf said. “I urge Pennsylvanians to monitor local weather and traffic conditions before making any plans and prepare for potential flooding.”The heaviest rain looks to affect the area Wednesday night into Thursday morning — with the highest totals across Pennsylvania. Ida is expected to exit the area by late Thursday afternoon and behind it will be the nicest weather the region has seen in weeks.
