SITUATION OVERVIEW
------------------
Irma is expected to have a significant impact across a large portion
of the Florida big bend and southern Georgia with widespread wind damage
to numerous trees and power lines. Widespread and extended power outages
are expected. Winds of at least 40 MPH may begin as early as Sunday
evening, but the worst conditions will be on Monday with wind gusts
well above hurricane force possible. Such winds can bring down large
tree limbs, trees, and power lines, leading to power outages and
impassable roads. The strongest winds are likely to be east
of the Apalachicola and Chattahoochee Rivers. Conditions will gradually
improve Monday night as a weakening tropical storm Irma moves northward
into central Georgia.
POTENTIAL IMPACTS
-----------------
* WIND:
Protect against life-threatening wind having possible devastating
impacts across the Eastern Big Bend of Florida. Potential impacts in
this area include:
- Widespread structural damage to buildings in the area. Numerous
with complete roof and wall failures. All mobile homes
destroyed. Damage greatly increased by large airborne
projectiles. Locations affected may be uninhabitable for weeks
or months.
- Large swaths of trees snapped uprooted with roadway signs blown
over.
- Nearly all primary and all secondary roads will be impassable.
- Widespread power and communication outages; potentially lasting
for weeks.
Also, protect against life-threatening wind having possible limited
to extensive impacts across inland North Florida and Southwest Georgia.
Potential impacts in this area include:
- Numerous large trees snapped or uprooted with roadway signs
blown over.
- Some primary and many secondary roads are impassible due to
debris.
- Significant power and communication outages; potentially
lasting for weeks.
* SURGE:
Protect against life-threatening surge having possible significant
impacts across the coast of the Florida Big Bend. Potential impacts in
this area include:
- Areas of inundation from storm surge flooding, compounded by
higher waves. Non-elevated homes and businesses along the coast
will be subject to flooding primarily on the ground floor.
- Sections of coastal highways and access roads will be flooded
with portions washed out, isolating affected coastal
communities.
- Moderate beach erosion with damage to the dune line.
- Moderate damage to marinas, docks, and piers. Small craft not
secured prior to the storm will break away from moorings.
Elsewhere across Eastern Florida Panhandle...Florida Big
Bend...Southeastern Alabama and Southwestern Georgia, little to no
impact is anticipated.
* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible
significant impacts across Eastern Florida Panhandle...Florida Big
Bend...Southeastern Alabama and Southwestern Georgia. Potential
impacts include:
- Rivers and associated tributary creeks and stream will rise and
overflow into the flood plain. Runoff will put stress on area
holding ponds and drainage ditches, increasing the likelihood
of widespread urban flooding.
- Flood waters will impact structures in low lying areas, as well
as those in the flood plain, possibly entering buildings. Urban
flooding will result in several road closures and some
washouts. A few overpasses may be weakened by fast moving flood
waters. Driving conditions are very dangerous.
* TORNADOES:
Protect against a tornado event having possible limited impacts
across portions of South Central Georgia and the Eastern Big Bend of
Florida. Potential impacts include:
- Isolated tornadoes are expected, resulting in a notable impact
to affected communities.
- Isolated areas affected by tornadoes will experience minor
damage, including some damage to structures and sporadic power
and communication outages.
- A few structures will be damaged by tornadoes, mainly with loss
of shingles or siding. Some mobile homes will be significantly
damaged, especially those unanchored. Large trees will be
snapped or uprooted.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
For those under evacuation orders, leave as soon as practical with
a destination in mind. Gas up your vehicle well ahead of time. Be
sure that you take all essential materials from your emergency
supplies kit. Let others know where you are going and when you
intend to arrive.
For those not under evacuation orders, understand that there are
inherent risks to evacuation (such as traffic congestion,
accidents, and driving in bad weather), so evacuate only if
necessary. Help keep roadways open for those that are under
evacuation orders.
* OTHER PREPAREDNESS INFORMATION:
Now is the time to bring to completion all preparations to protect
life and property in accordance with your emergency plan.
Outside preparations should be wrapped up as soon as possible before
weather conditions completely deteriorate. Any remaining evacuations
and relocations should be expedited before the onset of tropical
storm force wind.
If you are relocating to safe shelter, leave as early as possible. If
heading to a community shelter, become familiar with the shelter
rules before arrival, especially if you have special needs or own a
pet. Take essential items with you from your Emergency Supplies Kit.
Check the latest weather forecast before departing.
If you are a visitor and still in the area, listen for the name of
the city or town in which you are staying within local news updates.
Be sure you know the name of the county or parish in which it
resides. Pay attention for instructions from local authorities.
Closely monitor NOAA Weather radio or other local news outlets for
official storm information. Be ready to adapt to possible changes to
the forecast.
