Atmospheric River to Begin to Impact the Northwest U.S.; Gusty Winds in the Northeast U.S.

A strong atmospheric river moving into northern California later Tuesday will bring a threat for moderate to heavy rainfall and flooding, gusty to high winds, and mountain snows for parts of the Northwest U.S. through at least Wednesday. Gusty winds and isolated rain and snow showers will continue in the Northeast U.S. Tuesday behind a cold front. Read More >

Nor'easter
May 11-13, 2008

Synopsis

A low pressure system was centered over the Illinois/Indiana border early on the morning of May 11th and was moving towards the east. A seconday low began to form over eastern North Carolina during the late afternoon on the 11th and eventually absorbed the other low pressure becoming the dominant low. This low began its movement up the Mid-Atlantic coastline late on the 11th into the 12th. Early on the morning of the 12th the low was centered over the southern Delmarva with yet another low forming offshore. With the two lows in close proximity, a strong northeast wind developed and persisted through the evening of the 12th. The prolonged northeast flow combined with higher than normal tides caused tidal flooding in New Jersey and Delaware. There was limited moisture inland from the center of the system but an abundance of moisture was ushered into southern Delaware and Eastern Maryland. By Monday evening the coastal low began moving towards the southeast away from the region, bringing an end to the gusty winds and tidal problems.

Significant Impacts/Aspects

This was an interesting system as it will probably be remembered as the Mother's Day Storm 2008.

The most significant result of this system was a Coast Guard rescue off the coast of Rehoboth Beach, Delaware. A research vessel was damaged and began taking on water early on the morning of the 12th. The 2 crewmen had to be rescued and taken to the hospital, where one was later decared deceased.

Heavy rain combined with high astronomical tides caused several roads to close in Southern New Jersey and Delaware. Some major impacts from the flooding were:

Evacuations took place in Kitts Hummock, Bowers Beach and Woodland Beach in Kent County, Delaware due to coastal and road flooding.

The Indian River Inlet Bridge on Del 1 in Sussex County, Delaware was closed due to flooding.

Del 9 was closed at the Reedy Point Bridge in New Castle County, Delaware.

Coastal Flooding in New Jersey was comparable to the October 2006 floods.

Beach erosion in Delaware and New Jersey due to the high surf has also been attributed to this storm.

A limited State of Emergency was declared in Cape May County, New Jersey due to high winds and coastal flooding and was in effect from 200 PM EDT May 12th through 1000 AM EDT May 13th.
