Down 12mb in 9 hrs. 6mb in last 3hrs. It's hard to tell because the radar down there sucks, but it looks like the center of the storm has stayed off sure, which doesn't help to weaken it at all. Once this thing clears the Yucatan, it's game on.

Judging by Radar and satellite, the center is about 40mi/64km off the coast.

instructions from local officials.

A Hurricane Warning means that hurricane conditions are expected
somewhere within the warning area.  A warning is typically issued

your national meteorological service.


DISCUSSION AND OUTLOOK
----------------------
At 1000 AM CDT (1500 UTC), the center of Hurricane Helene was
located near latitude 21.6 North, longitude 86.3 West.  Helene is
moving toward the north-northwest near 10 mph (17 km/h).  A turn
toward the north and north-northeast with an increase in forward
speed is expected later today through Thursday, bringing the center
of Helene across the eastern Gulf of Mexico and to the Florida Big
Bend coast by Thursday evening.  After landfall, Helene is expected
to slow down and turn toward the northwest over the southeastern
United States Friday and Saturday.

Data from NOAA and Air Force Reserve Hurricane Hunter aircraft
indicate that maximum sustained winds have increased to near 80 mph
(130 km/h) with higher gusts.  Additional strengthening is
forecast, and Helene is expected to be a major hurricane when it
reaches the Florida Big Bend coast Thursday evening.  Weakening is
expected after landfall, but Helene's fast forward speed will allow
strong, damaging winds, especially in gusts, to penetrate well
inland across the southeastern United States, including over the
higher terrain of the southern Appalachians.

Hurricane-force winds extend outward up to 25 miles (35 km) from the
center and tropical-storm-force winds extend outward up to 275 miles
(445 km).

The minimum central pressure based on dropsonde is 979 mb (28.91
inches).


HAZARDS AFFECTING LAND
----------------------
Key Messages for Helene can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC
and on the web at hurricanes.gov/text/MIATCDAT4.shtml

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline.  The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Carrabelle, FL to Chassahowitzka, FL...10-15 ft
Chassahowitzka, FL to Anclote River, FL...6-10 ft
Indian Pass, FL to Carrabelle, FL...6-10 ft
Anclote River, FL to Middle of Longboat Key, FL...5-8 ft
Tampa Bay...5-8 ft
Middle of Longboat Key, FL to Englewood, FL...4-7 ft
Englewood, FL to Flamingo, FL...3-5 ft
Charlotte Harbor...3-5 ft

For a complete depiction of areas at risk of storm surge inundation,
please see the National Weather Service Peak Storm Surge Graphic,
available at hurricanes.gov/graphics_at4.shtml?peakSurge.

Storm surge could raise water levels by as much as 2 to 4 feet above
normal tide levels in areas of onshore winds along the southern
coast of Pinar del Rio, Cuba, including the Isle of Youth.

Storm surge could raise water levels by as much as 2 to 4 feet above
ground level in areas of onshore winds within the warning area along
the east coast of the Yucatan Peninsula.

WIND: Hurricane conditions are expected within the U.S. hurricane
warning area late Thursday, with tropical storm conditions
beginning Thursday morning.  Tropical storm conditions are
expected in southern Florida later today and will spread northward
across the rest of Florida, Georgia, and South Carolina through
Thursday.  Tropical storm conditions are possible within the
tropical storm watch area in South Carolina beginning on Thursday.

Hurricane conditions, especially in gusts, are expected in the
hurricane warning area in Mexico during the next several hours.
Tropical storm conditions are occurring in the warning area in Cuba,
and hurricane conditions are possible for the western portion of
Cuba today.

RAINFALL: Helene is expected to produce total rain accumulations of
4 to 8 inches over western Cuba, the Cayman Islands, and the
northeast Yucatan Peninsula, with isolated totals around 12 inches.
This rainfall brings a risk of considerable flooding.

Over the Southeastern U.S. into the Southern Appalachians, Helene
is expected to produce total rain accumulations of 5 to 10 inches
with isolated totals around 15 inches. This rainfall will likely
result in areas of considerable flash and urban flooding, with areas
of significant river flooding. Landslides are possible in areas of
steep terrain in the southern Appalachians.

For a complete depiction of forecast rainfall associated with
Helene, please see the National Weather Service Storm Total Rainfall
Graphic, available at hurricanes.gov/graphics_at4.shtml?rainqpf and
the Flash Flood Risk graphic at
hurricanes.gov/graphics_at4.shtml?ero.

TORNADOES: A tornado or two may occur tonight over parts of the
Florida Peninsula and southern Alabama. The risk of tornadoes will
increase on Thursday, expanding northward across Florida into parts
of Georgia and South Carolina.

SURF: Swells generated by Helene will affect the southern coast of
Cuba and the Yucatan Peninsula of Mexico during the next couple of
days.  Swells will spread northward toward the west coast of Florida
and the northeastern Gulf Coast later today and Thursday. These
swells are likely to cause life-threatening surf and rip current
conditions.  Please consult products from your local weather office.

This storm is massive, and will effect the entire state of FL. It will also effect almost the entirety of the SE US, up into the TN Valley.

I lived in Atlanta during Opal, and the amount of tree damage was massive.

It is doing exactly what the EXPERTS said it would.

Yeah, I remember some models having it drop to like 888 and even the experts questioned if there was something wrong with the model, just because it'd have to drop so much so fast. Think everyone is hoping it's wrong.

The 10am update moved it more west, with a direct hit on Tallahassee. Better for WDW and Tampa Bay, but not for the capitol.

A Cat 3 125mph 15 ft storm surge is life threatening and hopefully all residents and tourists heeded the orders to mandatory evac in the (3) coastal countries expected to take the direct hit.

I’m here myself till Friday so well aware. Just saying we have people always making wild predictions every time there’s the possibility of a hurricane, and viewers of this thread trying to figure things out for their trip should be reminded that everything posted here is speculative. Heck last time we had people recommending people look up where storm shelters were for what turned out to be a wet afternoon.

Dumb question, but as a person with tickets to this, where do you see the cancelation on the app and/or website?

Not doubting you, just have a sort of annoyed husband and want to show him the proof of cancelation 😬
