The 5AM advisory continues to show Dorian remaining just barely offshore which, if true, would spare the Florida Coast from the worst of the worst. That said, coastal impacts will be significant; and of course any deviation could make for massive differences in the effects.
For the central attractions area, Osceola County is now under a tropical storm warning. The other counties remain under watches, but those may be updated later today. The earliest reasonable arrival time for Tropical Storm force winds is very late tonight, although Tuesday morning is more likely. Overall, there’s about a 70% or 80% chance we’ll see winds of 39-73 MPH. The risk of hurricane force winds this far inland is less than 20%. Read on for county by county impact statements from the NWS.
Any final preparations for the central attractions area should be made by midday.
Notes from the NHC about the track:
Steering currents have weakened, and Dorian has almost come to a standstill over eastern Grand Bahama Island, with an initial motion of 270/1 kt. The mid-tropospheric high to the north of the hurricane that had been steering Dorian westward has collapsed. Global models indicate that, in a couple of days, a weakness in the ridge will develop along 75W-80W. This would likely cause Dorian to move northwestward to northward toward and through this weakness. Later in the forecast period, the system is expected to accelerate northeastward on the southern side of a broad mid-tropospheric trough. The official track forecast is very close to the previous one and to the corrected dynamical model consensus, HCCA. Although the official forecast does not show Dorian making landfall along the Florida east coast, it is still possible for the hurricane to deviate from this forecast, and move very near or over the coast. Users are reminded not to focus on the exact forecast track.
Key messages:
1. A prolonged period of catastrophic winds and storm surge will continue to affect Grand Bahama Island through today and tonight. Everyone there should remain in shelter and not venture into the eye. 2. Life-threatening storm surges and dangerous hurricane-force winds are expected along portions of the Florida east coast through mid-week, and storm surge and hurricane warnings are in effect. Only a slight deviation to the left of the official forecast would bring the core of Dorian near or over the Florida east coast. Residents should listen to advice given by local emergency officials. 3. There is an increasing likelihood of strong winds and dangerous storm surge along the coasts of Georgia, South Carolina, and North Carolina later this week. Residents in these areas should continue to monitor the progress of Dorian and listen to advice given by local emergency officials. 4. Heavy rains, capable of producing life-threatening flash floods, are expected over northern portions of the Bahamas and coastal sections of the Southeast and lower Mid-Atlantic regions of the United States into Friday.

**CATEGORY 5 DORIAN CONTINUES TO HAVE DEVASTATING IMPACTS ON GRAND
BAHAMA ISLAND**
NEW INFORMATION
---------------
* CHANGES TO WATCHES AND WARNINGS:
- None
* CURRENT WATCHES AND WARNINGS:
- A Tropical Storm Watch is in effect for Highlands and Polk
* STORM INFORMATION:
- About 210 miles east of Sebring FL or about 235 east of Winter
- 26.6N 78.2W
- Storm Intensity 165 mph
- Movement West or 270 degrees at 1 mph
SITUATION OVERVIEW
------------------
Major Hurricane Dorian is forecast to continue to move slowly west
through the northern Bahamas and then turn north just off the Florida
east coast by early Tuesday. At this time the primary concern is for
tropical storm force winds over Highlands County and eastern portions
of Polk County.
POTENTIAL IMPACTS
-----------------
* WIND:
Prepare for dangerous wind having possible significant impacts across
eastern Polk and Highlands Counties. Potential impacts in this area
include:
- Some damage to roofing and siding materials, along with damage
to porches, awnings, carports, and sheds. A few buildings
experiencing window, door, and garage door failures. Mobile
homes damaged, especially if unanchored. Unsecured lightweight
objects become dangerous projectiles.
- Several large trees snapped or uprooted, but with greater
numbers in places where trees are shallow rooted. Several
fences and roadway signs blown over.
- Some roads impassable from large debris, and more within urban
or heavily wooded places. A few bridges, causeways, and access
routes impassable.
- Scattered power and communications outages, but more prevalent
in areas with above ground lines.
Elsewhere across West Central and Southwest Florida, little to no
impact is anticipated.
* FLOODING RAIN:
Prepare for locally hazardous rainfall flooding having possible
limited impacts across eastern Polk and Highlands Counties. Potential
impacts include:
- Localized rainfall flooding may prompt a few evacuations.
- Rivers and tributaries may quickly rise with swifter currents.
Small streams, creeks, canals, and ditches may become swollen
and overflow in spots.
- Flood waters can enter a few structures, especially in usually
vulnerable spots. A few places where rapid ponding of water
occurs at underpasses, low-lying spots, and poor drainage
areas. Several storm drains and retention ponds become
near-full and begin to overflow. Some brief road and bridge
closures.
Elsewhere across West Central and Southwest Florida, little to no
impact is anticipated.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
WATCH/WARNING PHASE - For those not under evacuation orders, assess
the risk from wind, falling trees, and flooding at your location. If
you decide to move, relocate to a safer location nearby. If you do not
relocate, help keep roadways open for those under evacuation orders.
* OTHER PREPAREDNESS INFORMATION:
Now is the time to check your emergency plan and emergency supplies
kit and take necessary actions to protect your family and secure your
home or business.
When making safety and preparedness decisions, do not focus on the
exact forecast track since hazards such as flooding rain, damaging
wind gusts, storm surge, and tornadoes extend well away from the
center of the storm.
If in a place that is vulnerable to high wind, such as near large
trees, a manufactured home, upper floors of a high-rise building, or
on a boat, plan to move to safe shelter.
If you live in a place particularly vulnerable to flooding, such as
near the ocean or a large inland lake, in a low-lying or poor
drainage area, or near an already swollen river, plan to move to safe
shelter on higher ground.
Always heed the advice of local officials and comply with orders that
are issued. Do not needlessly jeopardize your life or the lives of
others.
When securing your property, outside preparations should be concluded
as soon as possible before conditions deteriorate. The onset of
strong gusty winds or flooding can cause certain preparedness
activities to become unsafe.
Be sure to let friends and family members know of your intentions for
weathering the storm and your whereabouts. Have someone located away
from the threatened area serve as your point of contact. Share vital
contact information with others. Keep cell phones handy and charged.
Check on those who may not be fully aware of the situation or who are
unable to make personal preparations.
If you are a visitor, know the name of the county or parish in which
you are located and where it is relative to current watches and
warnings. If staying at a hotel, ask the management staff about their
onsite disaster plan. Listen for evacuation orders, especially
pertaining to area visitors.
