Tropical Storm Debby makes landfall in Florida

Posted by: Angela Fritz, 9:07 PM GMT on June 26, 2012

+39

Debby continues to weaken this afternoon, but remains a tropical storm with maximum sustained winds of 40 mph. The storm's center of circulation made landfall this afternoon near Steinhatchee, Florida. Hurricane hunters continue to find surface wind speeds that just meet tropical storm criteria and surface buoys on Wundermap are all clocking in at or below 30 mph. The storm's upper-level circulation is being stretched out into the Atlantic by the same steering forces that will transport it to the other side of Florida, and this combined with dry air has led to a messy-looking tropical cyclone over the past couple of days. Though there was no lack of rain yesterday in the Florida panhandle, Debby has certainly been weakened by the dry air that has wrapped into its center (figure 1). Water vapor imagery from satellite shows Debby's center is almost completely void of moisture, though rain continues to fall on the northeast side of the storm where moisture is still available. A 6 foot wide, 12-15 foot deep sinkhole swallowed a small portion of I-10 in Madison County west of Jacksonville, Florida, this morning, where heavy rain continues, though this hole will likely be filled and the lane reopened by tomorrow morning. Wind shear around 20 knots is also keeping Debby at bay, but the real disrupter is the lack of moisture.

Figure 1. Where's Debby? On the left: visible satellite imagery. On the right: water vapor satellite imagery, where the dry air ranges from black to rusty orange. Debby's center is almost completely void of moisture. These images were captured around 1pm EDT.

Forecast for Debby
The forecast for Debby continues to be similar to previous forecasts. The storm will likely continue to lose strength as it moves over Florida this evening and Wednesday, but could gain some momentum again when it reaches the yet untapped Atlantic water. There's a high chance Debby will be downgraded to tropical depression status this evening. The HPC continues to forecast up to 8 inches of rain for far northeast Florida over the next 5 days, likely because of the slight strengthening forecast to occur on Thursday and beyond. Debby's center will most likely be over Atlantic water Wednesday night.

The Heat Continues

Record highs continue to fall Tuesday afternoon in the central U.S., where Denver, Colorado had its fifth consecutive day of triple-digit heat after it reached 100°F at 1pm MDT, and could continue to rise this afternoon. This ties the all-time record for consecutive 100°F+ days. Nebraska and Kansas are particularly toasty this afternoon; McCook, Nebraska has reached 113°F so far, and Hill City, Kansas is up to 112°F. Though, to put that in perspective, the state record for Nebraska is 118°F, and the state record for Kansas is 121°F.

The heat moves east tomorrow, and by Thursday, many of the major Midwest cities are forecast to be in the triple-digits, including Chicago, St. Louis, and Indianapolis. By Friday the heat will be beating down on the East Coast. In the meantime out west, the forecast high in Fresno for this weekend is 82°F, which would tie as the coolest final weekend in June on record, according to the Hanford forecast office.

You know what that means? I'm staying my butt indoors or in the pool. Oh come on, it's not that bad. I work in this heat almost every day and had a pretty epic Ultimate Frisbee Tournament yesterday.

Quoting weatherh98: pools are too hot Debby lowered my pool temp to 64º F! Heat wave should warm it back up. Just drove around the neighborhood here in Jax near the Intracoastal and the flood waters were marked by debris 4-5' up on people's lawns! Our lake drainage systems caught up with the rain but were up 4-5' too. There's also a creek in my 'hood that's usually very shallow and slow--today it's about 6 feet deep with black/brown water and rapids. If it wasn't for disease, snakes, drowning, poop and debris I'd consider tubing. Member Since: August 21, 2005 Posts: 0 Comments: 526

I threw New Jersey out there as a joke...........Louisiana as a top state, I would have to disagree. Hot, very hot, and burning hot in summer, big hurricanes seems to really like Louisiana too. Northwest Louisiana is technically in tornado alley and the state, as a whole ranks high for states that get tornadoes. If you like the seasons, Louisiana isn't the place either.

There's a rather largish storm moving toward Colorado Springs from the southwest. It's still hours away, but if it can hold together that might be good. Or not; a microburst from a collapsing storm in the mountains can causing devastating wind gusts to move across the fire area and cause a massive blow-up. Anyway, a the moment there's no rain in the fire area. From atop Pikes Peak: Member Since: November 8, 2009 Posts: 4 Comments: 11166

Link I wouldn't count Debby out just yet...look at how she is firing thunderstorms on the south end of her center. She seems to be ventilating quite nicely for a tropical depression. She is sitting in an area of decreasing shear, and as it is, it is a moderate 20 kts. We will see her upgraded again to TS at 5:00. Can anyone tell me how she has contributed to this year's ACE?

Quoting Neapolitan: The blast furnace continues, shifted a bit to the east from yesterday. Again, every station in Texas, Oklahoma, and Kansas should see triple digits today, along with many/most stations in Iowa, Missouri, Arkansas, and Louisiana. The good news (if there is any): fire-weary Colorado should be slightly cooler today (though that's a relative term; it'll still be very hot, with a wide swath of 100-degree-plus temps in the eastern third of the state). Hill City, KS, was already at 111 as of 1:00 PM. one saving grace i've noticed is dewpoints are very low... there's a small comfort in knowing the 'feels like' temp is lower than the actual temp :/ those humid blasts are what get me the most, with upper 90's feeling as hot as the actual temps occurring now, when sweating does nothing.. these dewpoints are Not good for the fire situation though.. hoping for that rain you just hinted at!

Vis Loop Interestingly enough, there is some model support for this...it appears as though the BAMM has this solution. I think this is a highly unlikely circumstance, but if it were to happen, BAMM projects Debby to come ashore at about the latitude of Lake Okeechobee.
