Danny absorbed by nearby low

Tropical Depression Danny 

Poor Danny. The fourth tropical storm of the 2009 Atlantic season has been torn apart and absorbed by a low-pressure system along the cold front pressing in from the west, in the Carolinas. The storm has lost its tropical characteristics. Its winds have dropped below tropical storm force, and the National Hurricane Center has dropped all TS watches and warnings.

So much for Danny. But for the record, all the storm's moisture is being drawn into the frontal low - now a tropical depression - which will mean plenty of rain and humidity for everyone in its path.

What's left of Danny was centered about 80 miles southeast of Cape Hatteras Saturday morning, with top sustained winds of 35 mph. The "extratropical low" was expected to accelerate to the north northeast, and then the northeast at 30 to 35 mph.

Here is the final advisory on Danny. Here is the forecast storm track. And here is the view from orbit.

The mid-Atlantic is not totally out of the woods on this thing yet. Rough surf and rip currents remain a hazard. Here is a bit of this morning's Coastal Flood Statement from Wakefield, Va.:

"DANGEROUS LONG PERIOD SOUTHEAST SWELLS...GENERATED FROM WHAT WAS
TROPICAL STORM DANNY...WILL CONTINUE THROUGH TODAY. BREAKING WAVES
IN THE SURF ZONE ARE EXPECTED TO AVERAGE 3 TO 4 FT. AS A RESULT OF
THE MODERATE WAVES AND LONG PERIOD SWELL...A HIGH RISK OF RIP
CURRENTS REMAINS IN EFFECT."

Here's the gray and soggy forecast for Ocean City.

Staying home won't improve the forecast much. Baltimore can expect another gray, wet day today, too. The risk of more heavy rains appears to be waning, at least. Here's the forecast. And here is the Hazardous Weather Outlook.Presque Isle State Park

We've ready had 1.5 inches here on the WeatherDeck since Thursday. Ditto for the airport. Here are some rain totals for the last 24 hours across Maryland. Some locations reported more than 2 inches. Forest Heights, in PG County, topped 3 inches.

Sunday's forecast here looks better, with a bit of sunshine and no rain predicted. But the rest of the week looks more iffy, with at least some rain chances every day as we remain stuck beneath a stalled cold front. Temperatures, at least will be cooler - in the 70s.

Want a pleasant AND sunny week? Head for the beaches at Presque Isle, in Erie, Pa (above).

Its beginning to look at lot like Hurricane season...

Thanks- nice synopsis. I was wondering why for the past day or so the storm track on Weather Underground at

http://www.wunderground.com/tropical/tracking/at200905.html#a_topad

has had the storm center well south of where the greatest activity appears to be. see

http://www.wunderground.com/tropical/

and click on Atlantic Infared.

The system has appeared rather spread out, with no real center, thus the down-grade.

I'll email the images in case the links don't work.
