It’s a Soaker – More Northeast Flooding
Hello and happy Thursday everyone – hope all is well on this 10th of March. We continue to track this massive storm system as it shifts east. Heavy rain looks to be the primary threat now across the Northeast as updated forecast models are hinting at nearly 4″ to 5″ of additional rainfall for locations that were hit hard last weekend. Some of the river forecasts in the northeast, particularly the Susquehanna River at Wilkes Barre, will see some major water level rises within the next 24 to 48 hours. The Susquehanna is forecast to rise nearly 17ft. by late Friday night!
Out of the nearly 4800 total river gauges nationwide there are 164 locations that are in flood state, mainly through the Mississippi River Valley into the Ohio River Valley. We are likely to see a number of additional locations added to this list in a very short amount of time through the Northeast – keep track of the flooding HERE:
The significant river flooding outlook doesn’t look good – There are several locations through the Mississippi River Valley where flooding is already occurring and several locations in the Northeast is LIKELY through March 14th:
Flooding has already been problem in a few locations of the Northeast with this last weekends heavy rain – check out the flooding video from Sommers, CT below:
More Significant River Flooding is Expected
Flash Flood Guidance
This is an interesting map that is updated by the National Weather Service. It takes into account how saturated the ground is and how much additional water the ground can hold within a certain time period before giving way to flash flooding. The counties shaded in red or pink indicate regions where very little additional water is needed for flash flooding, in some cases only a little over 0.50″ in a 3 hour period (northern New Jersey) – the map below indicates additional rainfall needed in a 3 hour time to produce flash flooding – See here for more Flash Flood Guidance
How Much Rain Are We Talking?
The HPC QPF (Hydrological Prediction Center Quantitative Precipitation Forecast) from AM Thursday to AM Saturday shows a big blob heavy rainfall over areas that could do without this extra rain. Several locations will likely see 1″ to 3″ with a few unlikely locations receiving 4″ to 5″ by AM Saturday – YIKES!!
That’s all for today – thanks for checking in on this Thurday
