An intense nor'easter brought heavy rain and flooding to the Maryland Eastern Shore on the 15th and strong winds to the region on the 16th. Rain began falling during the evening on the 14th, but fell at its heaviest from about Midnight EDT through about 3 p.m. EDT on the 15th. The rain ended before sunrise during the early morning of the 16th. Event precipitation totals averaged between 3 and 6 inches. The strongest winds occurred as the nor'easter pulled northeast of the region on the 16th from the early morning into the afternoon. Peak wind gusts averaged around 50 mph.
The worst reported flooding was in Cecil County on the 15th where four roadways were closed (including Delaware Avenue) in Elkton as the Big Elk Creek flooded. Flooding was also reported along Maryland State Route 7 at Broad and Peddler Creeks in Charlestown. The Trinity Woods subdivision experienced yard and roadway flooding. Elsewhere similar flooding conditions occurred as mainly poor drainage, yard and field flooding was reported. The gusty northwest winds on Monday the 16th caused scattered power outages for both Delmarva Power and Choptank Electric Cooperative.
Storm totals included 5.63 inches in American Corner (Caroline County), 3.80 inches in Federalsburg (Caroline County), 3.50 inches in Stevensville (Queen Anne's County) and 3.37 inches at the Conowingo Dam (Cecil County). Peak wind gusts included 54 mph in Salisbury (Dorchester County), 53 mph at the Baltimore-Washington International Airport, 48 mph in Easton (Talbot County), 47 mph in Annapolis (Anne Arundel County) and 46 mph in Chesapeake City (Cecil County) and Tolchester Beach (Kent County).
The nor'easter low pressure system initially formed in the southern Rockies on the 12th and moved to Arkansas on the morning of the 14th. At 8 p.m. EDT on the 14th, there were two low pressure systems, one in Kentucky and the other in western Alabama. The southern low pressure system became the predominate one overnight and at 8 a.m. EDT on the 15th, it (996 millibar low) was located in western North Carolina. As the 15th continued, it moved northeast and intensified rapidly. At 2 p.m. EDT the nor'easter (989 millibars) was near Raleigh, North Carolina. At 8 p.m. EDT, the nor'easter was a 979 millibar low pressure system near Virginia Beach, Virginia. Another low pressure system formed on its warm front during the afternoon over Chesapeake Bay and at 8 p.m. EDT it (982 millibars) was over extreme southwest New Jersey. The lows consolidated into one again overnight and a very intense 973 millibar low pressure system was located over Monmouth County, New Jersey at 2 a.m. EDT on the 16th. At 8 a.m. EDT on the 16th the nor'easter was down to 968 millibars and located over New York City. That was a drop in central pressure of 28 millibars in 24 hours which qualified it as a meteorological bomb (a drop in central pressure of at least 24 millibars in 24 hours) low pressure system. The nor'easter bottomed at a pressure of about 966 millibars (28.53 inches) at 11 a.m. EDT just south of Long Island, New York. To put into prospective how low the pressure was with this nor'easter, that central pressure is near the border of the pressure defined category 2 and category 3 hurricane once used on the Saffir-Simpson Hurricane Scale. As the 16th continued, the nor'easter weakened and meandered across southwest New England and the New York and New Jersey coastal waters. By 2 a.m. EDT on the 17th, the nor'easter's central pressure rose to 988 millibars and a second storm formed on the triple point of its fronts south of Nova Scotia. This became the main low pressure system. The low pressure system then slowly moved southeast over the next couple of days. The heaviest precipitation fell as the low pressure system was rapidly intensifying on the 15th into the early part of the 16th. The strongest winds ceased after the low pressure system started to fill on the afternoon of the 16th.
