11 a.m. Hurricane Irma path from nhc.noaa.gov

From the National Weather Service:

 

…HURRICANE WATCH IN EFFECT…

…STORM SURGE WATCH IN EFFECT…

A Hurricane Watch means Hurricane wind conditions are possible

somewhere within this area and within the next 48 hours

A Storm Surge Watch means life-threatening inundation levels are

possible somewhere within this area and within the next 48 hours

* LOCATIONS AFFECTED

- Savannah Airport

- Hunter Army Airfield

- Bloomingdale

* WIND

- LATEST LOCAL FORECAST: Equivalent Tropical Storm force wind

- Peak Wind Forecast: 35-45 mph with gusts to 60 mph

- Window for Tropical Storm force winds: early Monday morning

until early Tuesday morning

- CURRENT THREAT TO LIFE AND PROPERTY: Moderate

- Emergency planning should include a reasonable threat for

strong tropical storm force wind of 58 to 73 mph.

- To be safe, earnestly prepare for the potential of

significant wind impacts. Efforts should now be underway to

secure all properties.

- Dangerous wind is possible. Failure to adequately shelter

may result in injury.

- POTENTIAL IMPACTS: Significant

- 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.

- Some roads impassable from large debris, and more within

urban or heavily wooded places. A few bridges and access

routes impassable.

- Travel by vehicle or on foot increasingly difficult. Danger

of death or injury from falling objects such as trees or

electric wires outside.

- Scattered power and communications outages, but more

prevalent in areas with above ground lines, which could

persist for hours or days.

- Some poorly secured small craft could break loose from

their moorings.

* FLOODING RAIN

- LATEST LOCAL FORECAST:

- Peak Rainfall Amounts: 4-8 inches, with locally higher

amounts

- CURRENT THREAT TO LIFE AND PROPERTY: Moderate

- Emergency planning should include a reasonable threat for

moderate flooding where peak rainfall totals notably exceed

amounts conducive for flash flooding and rapid inundation.

Rescues and emergency evacuations are possible.

- To be safe, earnestly prepare for the potential of

significant flooding rain impacts.

- Dangerous flooding is possible. Failure to take action may

result in serious injury or loss of life. If flood related

watches and warnings are issued, heed recommended actions.

- POTENTIAL IMPACTS: Significant

- Moderate rainfall flooding could prompt some rescues.

- Rivers and tributaries could quickly become swollen with

swifter currents and overspill their banks in a few places,

especially in normally vulnerable spots. Small streams,

creeks, canals, and ditches overflow.

- Flood waters can enter some structures or weaken

foundations. Several places could 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.

* TORNADO

- LATEST LOCAL FORECAST:

- Situation is favorable for tornadoes

- CURRENT THREAT TO LIFE AND PROPERTY: Moderate

- Emergency planning should include a reasonable threat for

scattered tornadoes, with a few possibly strong in

intensity.

- To be safe, earnestly prepare for the potential of

significant tornado impacts.

- Listen for tornado watches and warnings. Be ready to

shelter quickly if a tornado approaches.

- POTENTIAL IMPACTS: Significant

- Isolated to scattered tornadoes can hinder the execution of

emergency plans.

- Scattered locations could experience enhanced damage due to

tornadoes with a few spots of considerable damage, power

loss, and communications failures.

- Scattered locations could realize roofs torn off frame

houses, mobile homes demolished, boxcars overturned, large

trees snapped or uprooted, vehicles tumbled, and small

boats tossed about.
