#category5 #hurricaneotis
It looks as if the area of interest we have been tracking in the extreme southwestern Caribbean will have NHC Advisories issued and interests in Central America may want to prep for a "Category Slow" tropical cyclone, the center of which is presently just offshore and soon to be inland, eventually.

The National Hurricane Center has begun hourly position and
intensity updates on Idalia. The hourly updates will continue as
long as Idalia's eye is easily trackable in ground-based radar data.
...IDALIA FORECAST TO BECOME A MAJOR HURRICANE TONIGHT...
...CATASTROPHIC STORM SURGE AND DESTRUCTIVE WINDS LIKELY TOMORROW MORNING WHERE THE CORE OF IDALIA MOVES INLAND...
NOAA and Air Force Reserve Hurricane Hunter aircraft data indicate
that Idalia has strengthened further. Maximum sustained winds have
increased to 110 mph (175 km/h). The minimum pressure based on
dropsonde data from the aircraft has fallen to 960 mb (28.35
inches).

30 Years ago today Hurricane Andrew made landfall in South Florida, this radar is from when it approached. The radar stops at landfall because the radar was destroyed by the strong winds. It remains one of Florida's costliest disasters, particularly for Homestead. Nothing in Florida until Hurricane Michael on Mexico Beach has since reached that level of intensity in Florida.
#98L as it pushed inland this morning through early afternoon. Beautiful system bringing much needed rain to south Texas. Some locations already seeing flooding, however, and that is likely to continue.
Not yet Invest tagged. There have already been two disturbances this season that NHC did not upgrade in real-time that are very possibly candidates for post-season review (90L, 92L). This feature could be Invest tagged soon if trends persist. Already very much looks and acts like a T.D.
The Moderate and High Risk Flash Flood threat continues

SUMMARY...Tropical Storm Elsa. Significant flooding likely across
DISCUSSION...Surface center of Elsa is now starting to see a
disconnection from mid to upper level center as it races
northward...as such, boundary layer to 5H is sharpening on the
eastern hemisphere of the circulation with best deep layer
moisture convergence within the SE quadrant and focused on the
first outer band from Port Charlotte to Sanibel Island and
upstream into the Gulf. Prolonged training from Port Charlotte to
Manatee county has resulted in some observed reports of 5 to 7"
over the last few hours, matching well to MRMS along the band.
This has resulted in strong hydrological response with max unit
stream flow values over 600-1000 cfs/smi indicative of rapid
inundation and flash flooding...and over 200% of even the very
high FFG values in the region.
Trends on the Hi-Res CAMS have been supporting the 00z ARW/ARW2
versus the HRRR even with hourly assimilation, and so is the
preferred solutions moving forward over the next 3-6hrs across
Western Florida. Given position of 5H vort center along the SE
quadrant at this time, rotating north soon, deepest convergence of
the band will support some slow westward retrograde with a slow
northward shift. Concurrent with backing steering flow and less
deep southerly unidirectional flow may allow for greater
concentration of heaviest rainfall convective bands a bit off of
the worst affected areas. Still, CIRA LPW denotes Sfc-850mb
values over 1.25" which is about as high as observed though, dry
slot appears to be nosing further south across Naples, the 85-5H
layers show increased moisture on coastal Charlotte to Manatee
county supporting conditioned hourly rates of 2.5-3". This keeps
the greatest risk of rapid in
