Nor'easter Expected To Bring Heavy Rain, Strong Winds, Beach Erosion To The Northeast, Mid-Atlantic

 

 

An upper-atmospheric area of low pressure sliding southeast from the Great Lakes has spawned an area of low pressure. This low was over the Delmarva Peninsula late Tuesday evening and will quickly slide off the Atlantic coast, then remain off the New England coast through at least Thursday. The low will also intensify as it meanders off the Eastern Seaboard.
This low will combine with a strong surface high pressure system in eastern Canada to create a tight pressure gradient which will bring strong easterly to northeasterly winds into parts of the Northeast. This is an onshore wind for parts of New England, raising concerns for coastal flooding and beach erosion due to the prolonged duration and long fetch of these winds, particularly from the North Shore region of Massachusetts into Downeast Maine.
The subtropical jet stream will also move north which will bring tropical moisture northward, enhancing the rainfall across the region.
Anywhere from the northern Mid-Atlantic to New England will likely be affected by heavy rain and strong winds. The exact track of the low will determine the timing and location of the heaviest rain and strongest winds.
