Tropical Depression 3 Dissipates in late July
Posted: 09:30 AM 21 July 2019 | 3 Comments | Add Comment | Newest: 03:02 PM 22-Jul EDT
TD#3 has dissipated after recon found it falling apart.
There is an area in the Gulf with a 20% chance for development later in the week.
9:30 PM EDT 22 July 2019 Update
Tropical Depression 3 formed, and quickly lost convection after being upgraded. Although overnight it may regain some.
This is expected to remain offshore of Florida, and outside of right along the beach, should not be really noticeable to Florida.
The National Hurricane Center is mentioning a new area east of the Bahamas in the Outlook, with a 20% chance of development. This area, being designated Invest 94L, has no model support yet, but there is enough vorticity to make it worth watching.
If this were late August or September it probably be much more concerning. It's been mostly surrounded by dry air, but is gaining some moisture, but will likely remain squelched by dry air for the next few days. It's fighting a front coming up as well, so the chances for anything happening are quite low. But because of the location it's now designated 94L.
No real model support, but the chance for a small system ramping up is still there. Since it's near Bahamas and Florida it has our attention.
See The forecast lounge. for more speculation.
July 22nd 5PM EDT update - The NHC decided to classify the system in the Bahamas as Tropical Depression 3. Not much is expected from the system as it moves north for the next couple of days until it's likely absorbed by a frontal boundary.
However, interests along the Florida, Georgia, and Carolina coast should keep an eye on the system.

Hurricane Matthew Weather Summary for East Central Florida
Posted: 05:32 PM 16 October 2016
A low pressure reading of 28.97" was recorded at Melbourne NWS at 7AM. At 7:30AM I noted a pressure reading of 28.98" at my home in northwest Melbourne. The lowest pressure was located in the southern section of the eye of the hurricane and the central pressure from the Hurricane Hunters was recorded at 938MB (27.90") at 1AM. At 4AM the aircraft reported a circular eye with a diameter of 32NM and a central pressure of 942MB with flight level wind at 118 knots which translates to a 100 knot surface wind (115mph). At 7:17AM the aircraft sent a position fix for the eye at 28.6N 80.2W with a pressure of 942MB and eyewall sustained surface winds of 110 knots. The eye of Matthew had contracted to a circular 20NM diameter as the hurricane passed to the east of the area. Although the radius of the eye had contracted from 17NM to 10NM, the radius of sustained hurricane force winds remained at 40 miles to the west of the center. The central pressure increased and leveled off at 947MB during the day on Friday as Matthew moved NNW. If the eye of Matthew had moved along the shoreline, i.e., if it had been 35-40 miles further to the west, damage would have certainly been greater but no realistic conclusion can be made with regard to the extent of the destruction because an on-shore system would have slowly weakened.
Matthew goes into the record books as a Category I Hurricane in a small section of the Brevard County coast. In some reports from the NHC the flight level Recon wind speeds were not reduced correctly and resulted in stated maximum eyewall surface wind speeds that were about 10mph too high - and I cannot find a valid meteorological reason for doing this. Hurricane Erin in 1995 and Hurricanes Frances and Jeanne in 2004 were all storms with a greater impact on Brevard County. While the early call by the Brevard Emergency Management Operations Center to evacuate residents from the Barrier Islands was prudent, the overstated intensity and inland impacts were mis-leading and confusing to some of our residents. The National Hurricane Center and The Weather Channel both over-hyped the overall magnitude of the storm - which will not help folks to make the correct decision when the next hurricane visits our area. Matthew was not the catastrophic Category IV storm of the century that was touted by some for our area. All hurricanes are dangerous and deserve proper preparation and decision-making. It is worth noting that the area from Melbourne Beach to Titusville has never recorded a Cat III or greater hurricane. Someday that record of 165 years will probably be broken, but Matthew was not that storm. Hurricane David, September 3-4, 1979, was the last Category II Hurricane to hit this area with eye passage along the coast from West Palm Beach to New Smyrna Beach.

Hurricane Matthew - Getting Too Close For Comfort

Hurricane Matthew - It Could Get Interesting
Posted: 09:07 PM 03 October 2016
On Friday morning and early afternoon Matthew should move parallel to and about 50 miles offshore of the Florida east coast from Jupiter to Daytona Beach. Closest approach to east central Florida expected to be around 11Z (7AM) on Friday morning. Winds in east central Florida will be out of the Northeast on Thursday evening becoming more Northerly Friday morning peaking at 50mph gusting to 65mph on the barrier islands and 40mph gusting to 50mph inland near I-95. I expect that the National Hurricane Center will issue a Tropical Storm Watch (or Warning) for the eastern portion of the Florida peninsula late tonight or early Tuesday morning.
Rainfall totals in east Florida are expected to be in the 3 - 5" range with some localized flooding likely. Storm surge in the 3 to 5 foot range is possible on the barrier islands as the hurricane approaches and the surface winds increase out of the northeast. Boats should be secured for strong tropical storm force winds and high waves. Rip current threat will increase on Thursday and Friday. Loose objects, lawn chairs, etc., should be secured or stored on Tuesday and Wednesday. As the weather deteriorates, provide shelter for your pets.
Use Tuesday to check on your storm supplies and replenish as needed. Have an adequate supply of drinking water and batteries on hand - if the storm track adjusts more to the west you just might need these items. Monitor the progress of this hurricane closely - if a Category III hurricane rides up the coast and you are in its path, do you have an evacuation plan? Hopefully Matthew will stay far enough offshore and the impacts will be minimal but being prepared is always a smart choice.
Matthew & Models
Posted: 02:26 PM 01 October 2016
To repeat something that I've said before, the model is not the forecast - it is just a guide that is used to make the forecast. The models on this particular storm have not performed well. They missed the rapid intensification cycle that took place Friday evening - they missed the extended movement of the hurricane to the west southwest and even southwest at times - and they missed the cyclonic loop currently underway. These changes, whether subtle or sudden, are still difficult things to forecast and its important to remember that models are simply software programs that were developed by scientists. Just like weather forecasts, they are not perfect and precise and they were not intended to be - to base your forecast entirely on model output means that bad forecasts will occasionally be made.
Hermine Heads for Florida
Posted: 02:22 AM 01 September 2016
Sustained Tropical Storm winds are likely in Jacksonville and possible in St Pete/Tampa, Orlando and Daytona Beach. Wind gusts to tropical storm force in rain squalls (40 to 45mph) are possible along and north of a line from Ft Myers to Ft Pierce on Thursday. Scattered to numerous tropical downpours - a few with thunder - will produce rainfall amounts of 2 to 4 inches in east central Florida on Thursday and early Friday with much heavier amounts in west central and northeast Florida. Significant flooding is likely through Friday - especially in west central to northeast Florida. Hurricane force winds at landfall Thursday evening will create widespread power outages and flooded roadways in the Cross City to Jacksonville corridor. Isolated tornadoes are possible - mostly over the northern half of the peninsula - on Thursday
Most of the forecast models seem to have initialized Hermine's center too far to the west, and it is quite possible that Hermine may move slightly more to the right than I have indicated - which primarily would generate higher winds in west central Florida. A good guideline with this Tropical Storm is to extrapolate the current movement, whenever the storm turns more to the north northeast, and use that as the expected track since nothing is likely to move the storm to the left of that line.
