Central Alabama on Monday into Monday night. Winds of 35 to 45 mph may
begin as early as the pre dawn hours Monday in the southeast counties.
Conditions will worsen during the afternoon and evening on Monday as
strong winds spread northward with gusts possibly reaching 60 mph.
Scattered tree and power line damage is possible along with power
outages. Some minor structural damage is also possible. The greatest
wind gusts and impacts are expected to be generally along and east of a
line from Oneonta to Sylacauga to Montgomery to Troy. Conditions will
gradually improve on Tuesday as Irma continues to move northward.
POTENTIAL IMPACTS
-----------------
* WIND:
Protect against dangerous wind having possible significant impacts
across the far southeast counties general east of an Auburn to Clayton
line. 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.
Also, protect against hazardous wind having possible limited impacts
across generally east of an Oneonta to Sylacauga to Montgomery to Troy
65 and west of an Auburn to Clayton line.
* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible significant
impacts across the far east central counties in Central Alabama.
Potential impacts include:
- Moderate rainfall flooding may prompt several evacuations and
rescues.
- Rivers and tributaries may quickly become swollen with swifter
currents and overspill their banks in a few places, especially
in usually vulnerable spots. Small streams, creeks, canals,
arroyos, and ditches overflow.
- Flood waters can enter some structures or weaken foundations.
Several places may experience expanded areas of rapid
inundation at underpasses, low-lying spots, and poor drainage
areas. Some streets and parking lots take on moving water as
storm drains and retention ponds overflow. Driving conditions
become hazardous. Some road and bridge closures.
Protect against locally hazardous rainfall flooding having possible
limited impacts across most of the eastern half of Central Alabama.
* TORNADOES:
Little to no impacts are anticipated at this time across CENTRAL
ALABAMA.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
WATCH/WARNING PHASE - 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.
WATCH/WARNING PHASE - If you are exceptionally vulnerable to wind or
water hazards from tropical systems, consider voluntary evacuation,
especially if being officially recommended. Relocate to a
predetermined shelter or safe destination.
* 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.
Failure to adequately shelter may result in serious injury or loss of
life. Always heed the advice of local officials and comply with any
orders that are issued. Remember, during the storm 9 1 1 Emergency
Services may not be able to immediately respond if conditions are
unsafe. This should be a big factor in your decision making.
Check-in with your emergency points of contact among family, friends,
and workmates. Inform them of your status and well-being. Let them
know how you intend to ride out the storm and when you plan to
check-in again.
Keep cell phones well charged and handy. Also, cell phone chargers
for automobiles can be helpful after the storm. Locate your chargers
and keep them with your cell phone.
In emergencies it is best to remain calm. Stay informed and focused
on the situation at hand. Exercise patience with those you encounter.
Be a Good Samaritan and helpful to others.
If relocating to a nearby shelter or to the home of a family member
or friend, drive with extra caution, especially on secondary roads.
Remember, many bridges and causeways will be closed once higher winds
arrive. Also, if you encounter water covering the road, seek an
alternate route. Always obey official road signs for closures and
detours.
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.
