(10:30 p.m. update) Alberto located 770 miles south of Pensacola

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.
