The first numbers are starting to come in for Hurricane Irene's impact on Maryland, and Southern Maryland seems to have been hit hardest on rainfall.

BWI-Marshall Airport is reporting 4.6 inches of rain at 7 a.m. The heaviest rates were between 1 and 2 a.m., when 2.14 inches fell. Top sustained wind velocity was 30 mph, with gusts to 51 mph. The low barometer reading was 29.02 inches at 3 a.m.

The instruments at Ocean City Municipal Airport stopped reporting at 9 p.m. Not sure why. But the town's Office of Emergency Management issued a release this morning noting a rain total of 12 inches. Top sustained winds overnight were blowing at 60 mph, with gusts to 80.

With daylight, Ocean City officials were assessing damage at the resport. For now, the access routes onto the island remain closed until the damage assessment is complete and unsafe conditions secured.

Hurricane Irene made its second landfall at 5:35 a.m. near Little Egg Inlet, N.J., according to the National Hurricane Center in Miami. Winds were clocked at 75 mph. The barometric pressure there was 28.36 inches.
