PM Update: September starts off really hot

By Ian Livingston

Heat begins to back off Thursday; Earl approaches coast

* Earl now Cat. 4: Tropical Storm Warning for VA/MD/DE coast *
* Morning Hurricane Earl update | Hurricane Tracking Center *
* Warmest summer on record | The t'storm and the Battle of Oxen Hill *

5 PM Earl Update: Earl has strengthened to a Category 4 hurricane with maximum sustained winds near 135 mph. A Tropical Storm Warning is now posted for the VA/MD/DE beaches, where the timing of worst impacts would be late Thursday into Friday.

Today is day four of the current heat wave, the third day in a row with temperatures in the mid-90s, and day 58 this year of 90 degrees or higher at National Airport. Had enough? Well, too bad -- it's going to be hot forever. OK, OK, on a serious note, we should start stepping down tomorrow but it could still top 90 through Friday.

Through Tonight: Another very warm evening is ahead as readings fall into the 80s around sunset. We have picked up a bit more in the way of humidity, so temperatures probably stay up a smidge overnight. Look for lows in the upper 60s in the suburbs to the low-or-mid 70s downtown.

Tomorrow (Thursday): More mostly sunny skies visit the area. The heat wave should easily enter day five by midday with highs in the low 90s a good bet everywhere and perhaps a few mid-90s mixed in.

Hurricane Earl: As of 2 p.m. the center of Hurricane Earl was about 680 miles south southeast of Cape Hatteras, NC and moving northwest at 17 mph. While Earl weakened back to a Category 3 system this morning, with sustained winds of 125 mph, early afternoon data indicated the storm may attempt to re-strengthen to a Category 4, if only temporarily. Check out a cool video that NASA has posted which shows Earl from August 30 through today.

Ugh, zapped my first stink bug inside a short time ago. Apparently this time of year the little pests start looking for someplace warm to winter over. I haven't opened the windows for days; but they are opportunistic critters. Time to walk the walk and caulk the cracks!

The hurricane has strengthened to a category 4 and has shifted a good deal to the west. uh-oh

@Sandman, soon as CWG has a chance to take a look at the latest models, an Earl update would be helpful. Still looks like a "shore" event, though.

the NASA video is cool. For a time, Earl had a very sharp eye and symetrical feeder bands. Is there still a lot of relatively dry air off the coast that could knock Earl a few notches? How much of a change in course would give the DC area a taste of Earl?

Kinda' crazy this afternoon. With all the commercial channels focused on Silver Spring, no OCMs to tell us about Earl. This is one of the (few) days when I wish I had cable!

Raace to the Coast close or EARL!

Gaston has formed, and there's a system behind it.

Weather geeks, you can sleep when the season is over :-)

jaybird926 - agreed it is very active! It is like the atmosphere is making up for lost time (when it was quiet all season, till last week!)

jaybird926 - i can relate. I don't have cable either but sometimes the information is too expansive, lots to take in!--wish I had it today too.

Ok, CWG, I have a question. The weather channel keeps talking bout the worst possible scenario for Earl on the Outer Banks. The first graphics they show call for major damage, then they say, " Of course, if it continues to track this way, there still could be some damage." Which is it? No one talks probability.

The Weather Channel just cut off the Dare County Hurricane Prep guy in his conversation with Jim Cantore. I think it was because he was minimizing the danger to that portion of the Outer Banks, which sort of ties in with eor is saying.

Cantore is miffed that people are not preparing, while the small lower box on the screen shows Earl curving away.

Makes you think the projected path should include a buffer zone.

Thanks Jaybird, Cantore has been calling for the death of the Outer Banks, never mind the fact that it is a large chunk of teritory, so one evacuation on an island does not represent the area. I am probably going tomorrow (Manteo), if I do, I'll post from there.
