I haven't been paying attention.
Thanks for your work.
My Houston sister just flew to Tampa to spend the W/E with my sister there.
In before the whiners about storm hype.
Thanks for ping NN. Looks like it will be a TD when passes here.

Seems like this one came up all of a sudden.
Tampa area here: we had a huge downpour earlier this afternoon - had no idea it had a name. It was definitely intense, but as a Floridian for 11 years now it was just weather.
Sally’s update shows it’s track has shifted further east now - we’re dead center in the updated median. The AVNO 12/1200Z track has the center sitting literally on top of our roof Wednesday, but the 12/1800Z model has it doing a Crazy Ivan in the Montgomery/Birmingham area. Which puts us on the surly side of the circulation.
Sally - GO AWAY.
We’ve had enough from Laura already...

Hurricane Sally Discussion Number 14
NWS National Hurricane Center Miami FL AL192020
400 PM CDT Mon Sep 14 2020
After the rapid spin up of the inner core late this morning, the
most recent aircraft passes through the center have not found any
higher flight-level winds, however there have been a few SFMR winds
of 85-90 kt reported. Using a blend of the flight-level and SFMR
winds the initial intensity has been increased to 85 kt for this
advisory. The next Air Force and NOAA aircraft have begun to sample
the storm. Now that Sally has developed an inner core, the
favorable atmospheric and ocean conditions of low vertical wind
shear and warm water should allow for additional strengthening
tonight while the system moves over the north-central Gulf of
Mexico, and Sally could approach major hurricane strength. On
Tuesday, the global models are predicting an increasing in
southwesterly flow aloft, and this increase in shear, the potential
for land interaction, and some upwelling over the shallower shelf
waters over the northern Gulf should slow the intensification
process. The NHC intensity forecast is again near the upper-end of
the guidance envelope in best agreement with the HWRF and HFIP
corrected consensus models.
Sally did not move much earlier today as the center re-formation
took place, but it appears that a slow west-northwestward to
northwestward motion has resumed. Weak ridging over the
southeastern United States is expected to steer Sally generally
west-northwestward through early Tuesday. After that time, steering
currents weaken and a slow northward motion is forecast as a weak
mid-level trough develops over the the central United States. This
trough is forecast to slide eastward, allowing Sally to begin a
slow north-northeastward or northeastward motion. The specific
timing and location of the turn will be critical as to the eventual
location and timing of landfall along the north-central Gulf Coast.
The UKMET and ECMWF models show a more northeastward motion after
the turn and have trended eastward, with the ECMWF much slower than
the remainder of the guidance. The NHC track has been adjusted
eastward, and this requires and eastward extension of the hurricane
warning. The new track most closely follows the GFS and it ensemble
mean, but lies to the west of the various consensus aids, so some
additional eastward adjustments could be needed in subsequent
advisories.
Given the uncertainty in the timing and location of the northward
turn and the lack of well-defined steering currents, users are
reminded to not focus on the exact forecast track or the specific
timing and location of landfall. Hurricane-force winds, dangerous
storm surge, and flooding rainfall will affect a large portion of
the north-central Gulf Coast during the next few days.
KEY MESSAGES:
1. It is too early to determine where Sally’s center will move
onshore given the uncertainty in the timing and location of Sally’s
northward turn near the central Gulf Coast. Users should not focus
on the details of the official forecast track, since NHC’s average
forecast error at 36 to 48 hours is around 60 to 80 miles, and
dangerous storm surge, rainfall, and wind hazards will extend well
away from the center.
2. An extremely dangerous and life-threatening storm surge is
expected for areas outside the southeastern Louisiana Hurricane and
Storm Damage Risk Reduction System from Port Fourchon, Louisiana, to
the Okaloosa/Walton County Line in the Florida Panhandle, where a
Storm Surge Warning is in effect. Residents in these areas should
follow any advice given by local officials.
3. Hurricane conditions are expected late tonight or early Tuesday
within the Hurricane Warning area in southeastern Louisiana and are
expected by late Tuesday and Tuesday night within the Hurricane
Warning area along the Mississippi and Alabama coastlines and the
western Florida Panhandle. Tropical storm conditions are likely to
begin this evening in these areas and preparations should be rushed
to completion.
4. Life-threatening flash flooding is likely, as well as widespread
minor to isolated major flooding, on area rivers along and just
inland of the Central Gulf Coast. Significant flash and urban
flooding, as well as widespread minor to moderate river flooding is
likely across Mississippi and Alabama through the middle of the
week. Flooding impacts are expected to spread farther across the
Southeast through the week. Sally could continue to produce flash
flooding across the Florida peninsula and prolong existing minor
river flooding across west-central Florida through today.
