Somebody turn off the rain machine!
The epic rainfall that has hosed Central Maryland since Monday continued overnight. And it's not over yet.
The three-day total at BWI had reached 6.67 inches by midnight. We've had 5.74 inches here on the WeatherDeck in Cockeysville. But some locations have seen even more than that in just the past 24 hours.
The map at left is AccuWeather.com's Doppler radar estimate of rain totals for the 24 hours ending at 6 a.m. Thursday. No scale was provided, but you get the idea.
Somehow, it was not a record. BWI reported 3.40 inches of rain Wednesday. The Baltimore record for a Sept. 7 is 3.84 inches, set in 1934.
Many roads are closed this morning by high water or fallen trees. The WeatherDeck, and the four developments around us, were an island last night, blocked by high water from all directions. I - and perhaps 100 of my neighbors - didn't get home to our families and pets until the waters receded at 10 p.m. And I'm told by police that at least one of the exits is blocked again this morning by a fallen tree.
And forecasters say the relatively narrow plume of tropical moisture being channeled our way from Florida by the remnants of Tropical Storm Lee is still aimed right for us. (That's Hurricane Katia swirling off the coast.)
Here are some 24-hour rain totals reported this morning by the CoCoRaHS Network:
Waldorf, Charles County: 8.71 inches
Catonsville, Baltimore County: 7.87 inches
Ellicott City, Howard: 8.49 inches
Crofton, Anne Arundel: 7.00 inches
Elkridge, Howard: 6.78 inches
Severn, Arundel: 4.12 inches
Towson, Baltimore County: 3.74 inches
Mt. Airy, Carroll: 2.08 inches
Here's another tally from the National Weather Service, showing an unofficial Parkville station with a storm total of 9.42 inches.
The rain totals map above shows the heaviest amounts smack on top of the Susquehanna River watershed, so we can expect to see historic flooding in Harrisburg, and serious worries for communities as far downstream at Port Deposit in Maryland. Here's some of the thinking from AccuWeather.
