Published 10:45 pm Friday, May 25, 2018
Subtropical Storm Alberto was stationed about 770 miles south of Penscaola Friday evening.
The National Weather Service says Alberto is expected to move slowly northward toward the north central Gulf coast through Monday.
Alberton is currently forecast to move into coastal Mississippi and coastal Alabama early Monday evening.
The system will bring copious amounts of rain to the area mainly from Saturday night into Tuesday.
Storm surge inundation of 2 to 4 feet or higher is expected Sunday night into Monday.
Isolated tornadoes could be possible on Sunday night and Monday.
POTENTIAL IMPACTS
—————–
* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant
impacts across extreme southeast Mississippi, extreme southwest Alabama
and the western Florida panhandle. 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, 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.
Prepare for locally hazardous rainfall flooding having possible
limited impacts roughly north of Highway 84.
* SURGE:
Prepare for life-threatening surge having possible significant
impacts across coastal portions of Alabama and the western Florida
panhandle. Potential impacts in this area include:
– Areas of inundation with storm surge flooding accentuated by
waves. Damage to several buildings, mainly near the coast.
– Sections of near-shore escape routes and secondary roads become
weakened or washed out, especially in usually vulnerable low
spots.
– Major beach erosion with heavy surf breaching dunes. Strong and
numerous rip currents.
– Moderate damage to marinas, docks, boardwalks, and piers.
Several small craft broken away from moorings, especially in
unprotected anchorages.
Elsewhere across portions of southwest Alabama…northwest
Florida…south central Alabama…and inland southeast Mississippi.,
little to no impact is anticipated.
* WIND:
Prepare for dangerous wind having possible significant impacts across
portions of southwest Alabama…northwest Florida…south central
Alabama…and inland southeast Mississippi.. Potential impacts
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.
– Scattered power and communications outages, but more prevalent
in areas with above ground lines.
* TORNADOES:
Prepare for a tornado event having possible limited impacts across
portions of southwest Alabama…northwest Florida…south central
Alabama…and inland southeast Mississippi.. Potential impacts
include:
– The occurrence of isolated tornadoes can hinder the execution
of emergency plans during tropical events.
– A few places may experience tornado damage, along with power
and communications disruptions.
– Locations could realize roofs peeled off buildings, chimneys
toppled, mobile homes pushed off foundations or overturned,
large tree tops and branches snapped off, shallow-rooted trees
knocked over, moving vehicles blown off roads, and small boats
pulled from moorings.
PRECAUTIONARY/PREPAREDNESS ACTIONS
———————————-
* EVACUATIONS:
Listen to local official for recommended preparedness actions, including
possible evacuation. If ordered to evacuate, do so immediately.
* 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 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.
Closely monitor weather.gov, NOAA Weather Radio and local news
outlets for official storm information. Listen for possible changes
to the forecast.
