Ida's remains threaten once-in-a-century flood event in Northeast

After slamming into Louisiana with 150 mph winds, Ida has weakened below tropical depression status. But even though the winds are gone, the threat for significant flash flooding remains as the system pushes northeast. In fact, that threat will only grow larger as the tropical moisture merges with a jet stream diving south from the Great Lakes.
The expectation for widespread 4 to 8 inch rainfalls across some parts of the Mid-Atlantic and Northeast has prompted the National Oceanic and Atmospheric Administration's Weather Prediction Center to issue a rare "high risk" for torrential rainfall, warning that this could be a 1-in-100 year event for some areas.
On Tuesday night, the system was located over the eastern Tennessee Valley and Central Appalachians. The rain was falling moderately, but had yet to be supercharged by the impending jet stream. That will happen on Wednesday and Wednesday night.
Weather models are predicting 4 to 6 inches of rain over a widespread area, with isolated spots picking up over 8 inches. The heaviest rain looks to fall from the hills of northern West Virginia and Maryland, northeastward through Pennsylvania, northern New Jersey, southeastern New York and southern New England. This includes cities like Cumberland, Maryland, Harrisburg and Allentown, Pennsylvania, New York City and Hartford, Connecticut.
A rare high risk was issued by NOAA for the area shaded in purple.

(8,665 posts)The bulk of the storm moved north. But somewhere in the vicinity there are going to be some major flooding issues.
