Tropical Storm Danny still had not managed to pull itself together into a proper spiral Friday morning. And the central pressure in the storm (29.77 in.) wasn't much lower than the pressure out on the WeatherDeck in Cockeysville (29.99 in.)
Maximum sustained winds at the storm's center were barely 40 mph, only a few mph above falling back to the status of tropical depression. Here's some interesting discussion of Danny's troubles from the National Hurricane Center.
But Danny continues to move toward the Outer Banks, and its winds and waves will remain a threat to swimmers and boating along the mid-Atlantic Coast this weekend. Here is a bit of the forecast advisory this morning:
"LARGE SWELLS FROM DANNY ARE EXPECTED TO PRODUCE DANGEROUS SURF
CONDITIONS AND LIFE-THREATENING RIP CURRENTS ALONG THE U.S. EAST
COAST DURING THE NEXT DAY OR TWO. PLEASE CONSULT STATEMENTS ISSUED
BY YOUR LOCAL NATIONAL WEATHER SERVICE FORECAST OFFICE FOR MORE
While we slept .... assuming you could sleep with all the thunder and lightning ... the Baltimore region was visited by some impressive thunderstorms. We clocked 1.18 inches of rain on the WeatherDeck. The NWS instruments at BWI-Marshall recorded 1.4 inches.
Towson and Sykesville both reported an impressive 2.89 inches. Many locations across Central Maryland reported more than an inch of rain overnight. Here are some other measurements from the CoCoRaHS network.
