Debby dumps 20 inches of rain; 105° in Denver: hottest day on record

Florida, the Sunshine State, continues to be the thoroughly sodden state, thanks to torrential rains from slow-moving Tropical Storm Debby. On Monday, Debby spawned an area of intense thunderstorms that blew up over the Florida Panhandle, just east of Apalachicola. A weather station in Wakulia County, 4 miles east of Saint Marks, Florida, recorded 12.99" on rain in just 12 hours, bringing the 48-hour rainfall total at the site to 20.96". Several other stations in Wakulia Country also recorded rainfall amounts in excess of 20 inches, and the heavy rains caused moderate to major flooding on area rivers. Debby did not spawn any tornadoes on Monday, thankfully.


Figure 1. Radar-estimated rainfall from Tropical Storm Debby shows an area of extreme rainfall in excess of 15 inches has affected the Florida Panhandle.

Dry air and high wind shear continue to disrupt Debby. Our Wundermap for the surrounding ocean areas shows that winds at almost all buoys and coastal stations along the Gulf Coast were below 25 mph at 7 am EDT. Visible satellite loops show Debby has virtually no heavy thunderstorms near its center of circulation, which will severely limit its potential for intensification. The heavy thunderstorms of Debby are mostly on the east and north sides. Upper-level winds out of the west creating a high 20 - 25 knots of wind shear that continues to drive dry air into Debby's core. This dry air can be seen on Water vapor satellite loops. Ocean temperatures are about 27.5°C (81°F) in the Northern Gulf of Mexico, which is about 1°F above average, but these waters do not extend to great depth, which will limit how strong Debby can get.


Figure 2. True-color visible Terra satellite image of Debby taken at 12:30 pm EDT Monday June 25, 2012. At the time, Debby had top winds of 45mph. Note the heavy thunderstorms on the north side of the center, which were dumping extremely heavy rains over the Florida Panhandle that caused major flooding on area rivers. Image credit: NASA.

Forecast for Debby
Debby's slow motion will make rainfall the primary threat from the storm, though tornadoes will continue to be a threat over the next few days. NOAA's Storm Prediction Center has placed most of Florida in its "Slight Risk" area for severe weather today. The slow motion of Debby will inhibit intensification of the storm by stirring up cooler waters from the depths to the surface. Debby's close proximity to land places a portion of its circulation over land, which will also tend to slow down intensification. Wind shear is expected to remain in the high range through Wednesday, and given the storm's other problems, significant intensification before landfall on Florida's Gulf Coast is unlikely.

Denver's 105°: hottest temperature in city history
The mercury soared to 105° in Denver, Colorado on Monday, tying the record for the hottest temperature ever measured in the city. The city also hit 105° on July 20, 2005 and August 8, 1878. Yesterday's 105° reading was the city's fourth consecutive day in the triple digit heat. The city's record streak of 100°+ days is five, set in 1989 and again in 2005. Denver's forecast today calls for highs of 100 - 104°, so the city will likely tie its all-time mark for consecutive 100°+ days.

In many respects, the extreme heat that has scorched Colorado since Saturday is the state's most intense heat wave in recorded history. According to wunderground's weather historian Christopher C. Burt, Saturday's 114° reading in Las Animas tied for the hottest temperature ever measured in the state of Colorado. Two other 114° readings have occurred in Colorado history: in Las Animas on July 1, 1933, and in Sedgwick on July 11, 1954. Colorado Springs tied its all-time record for warmest temperature ever measured on both Saturday and Sunday, with readings of 100°. The record heat in Colorado has exacerbated numerous destructive wildfires, and the Governor reported over the weekend that half of the nation's firefighting fleet has been deployed to Colorado. On Sunday, a wildfire that grew to more than 3 square miles near Colorado Springs drove 11,000 residents (2% of the city's population) out of their homes. In Fort Collins, the mercury hit 102° on Sunday, just 1° below the city's all-time hottest temperature of 103° set on Jul 21, 2005. The heat did no favors for firefighters struggling to the contain the massive 81,000 acre High Park fire fifteen miles northwest of Fort Collins. The fire is the second largest and most destructive wildfire in Colorado's history, and is 45% contained. La Junta, CO hit 110° on Sunday, tying its all-time hottest temperature record, set on June 28, 1990. Today is the last day of exceptional heat for Colorado, as the ridge of high pressure responsible slides to the east, bringing record-breaking heat to the Midwest instead.

dont include me in that.
My forecast was correct until i gave in to the NHC, sees i should have stuck to my GFS.


I stuck with the GFS the whole time, just didn't post it here; but did manage to have disagreements with people face to face. In the end it does not matter. LOOK at the mess Debby is putting the NW coast of Florida and the panhandle though. Hurry up Debby and get out of there.

441. How about posting an image link that goes somewhere other than a site dedicated to art, which could be easily photoshopped... Maybe link an image from the original site, such as the NOAA or another organization that has direct access to the images (not rehosted images).

This is yesterday's satellite image of Greenland's coast showing pothole lakes, black carbon soot on the snow and massive run-off into the sea. The black carbon soot probably comes from coal fired power plants in India and China. Snow melts faster if it is painted black. There'll be some new real estate available in Greenland while some will be disappearing in Washington DC, no doubt.

Is Debby done with moving to the south? It seems like its going to make landfall north of Cedar Key....

I really hope everyone and everything gets back to normal soon. The best of luck to you and your family.
My pop-pop had a mini-stroke a few years ago and I can't imagine how bad it is for you. God bless you and your family.
I could never imagine so many bad things at once.
Because that's just unbelievable what happened.
My condolences to you.

Next time we have a storm, one of you who is bashing Levi's forecast should challenge him. It's not like his forecast was absurd. He was forecasting west before really any of the models went that way. The models shifted west towards his solution for several days. There were really only two solutions, left or right. For once, the GFS was right (no pun intended). Levi's track record speaks for itself, so I really don't have to defend him. I just find it funny that most of the people who were from Florida "wishing" the GFS were correct are beating their chests acting like they've done something to out-forecast Levi. Quite a joke, actually. Until you put in the time and effort that he does into this, you should probably have a seat and keep your mouth shut.

I live in South Central Texas. Yes, it hasn't rained (more than a trace) in 6-7 weeks. Everything around is brown and dead/dying from the last two years. I realize it isn't really the desert, but sometimes it hard to distinguish the differences :)

What is fun to watch is how all the rain is hanging out just barely off the SC coast. My radar shows two layers of activity. One being pulled off NE by the front and a lower level going NE to SW on shore of the main rains.

Port Richey, Florida -- Pasco County has issued a mandatory evacuation order due to excessive flooding for parts of the county.

Pasco County Sheriff's deputies, along with Emergency Services personnel, will be going door-to-door to provide a safe exit for residents to an emergency staging area at the Walmart at SR 54 and Little Road.

The evacuation order affects the communities just north of Trouble Creek Road, south to SR/Old 54, west to Rowan Road and continuing east to Sawgrass Blvd/Whitetail Lane in New Port Richey.

The order has also been extended for communities at risk for flooding between Anclote and Pithlachascotee rivers.

The boundaries are as follows:
•The western boundary of the evacuation area is the Anclote River/Thys Rd.
•The eastern boundary of the evacuation is Little Rd.
•The northern boundary is Plathe Rd.
•The southern boundary begins on Perrine Ranch Road and runs east to the intersection of Perrine Ranch Road, turns north on Seven Springs Boulevard, then runs east along Mitchell Ranch Road and continues east on S.R. 54 to the intersection of S.R. 54 and Little Rd.
•The evacuation order also includes other locations ordered evacuated by local authorities due to conditions posing a threat to life, health or safety.

Storm shelters have been set up at the following locations:
•Mike Fasano Hurricane Shelter located at 11611 Denton Ave, Hudson (pet-friendly shelter)
•Chasco Elementary School located at 7906 Ridge Rd, Port Richey

Public transit buses will be available to take residents from the staging to the shelters.

In addition sand and sandbags are available at:
•West Pasco Government Center, 7536 State St., New Port Richey
•7918 Rhodes Road, Hudson, Fire Station #10
•2952 Seven Springs Road, New Port Richey, Fire Station #17
•Mitchell Field (Park) located at 4711 Little Road

For more information, citizens can call the Resident Information Line at 727-847-8137. For emergencies, call 911.

While the law enforcement officers in the neighborhood will have the legal authority to compel people to leave, Pasco County Sheriff Chris Nocco tells 10 News officers don't plan to remove people who are thinking clearly and in no immediate danger.
