SITUATION OVERVIEW

Hurricane Irma is now a Category 2 over west central Florida near
Tampa Bay. The storm continues to move northward this late Sunday
evening and a gradual weakening trend is expected into the early
morning period Monday. The storm will continue its northward
track across western Georgia on Monday, and eventually cross into 
the Tennessee Valley Monday afternoon. The remnants of Irma will
continue to impact the Tennessee Valley Monday night into Tuesday,
as the system moves northwest towards the Mid South region. Strong
gusty winds and heavy rainfall associated with Irma will taper off
to the west late Tuesday afternoon into Tuesday evening as the system
exits the area.

POTENTIAL IMPACTS
-----------------

* WIND:
Potential impacts from strong hazardous winds include:
    - Damage to porches, awnings, carports, sheds, and unanchored 
      mobile homes. Unsecured lightweight objects blown about.
    - Many large tree limbs broken off. A few trees snapped or 
      uprooted, but with greater numbers in places where trees are 
      shallow rooted. Some fences and roadway signs blown over.
    - A few roads impassable from debris, particularly within urban 
      or heavily wooded places. Hazardous driving conditions on 
      bridges and other elevated roadways.
    - Scattered power and communications outages.

* FLOODING RAIN:
Potential impacts from hazardous flooding include:
    - Localized rainfall flooding may prompt a few evacuations.
    - Rivers and tributaries may quickly rise with swifter currents. 
      Small streams, creeks, canals, arroyos, and ditches may become 
      swollen and overflow in spots.
    - Flood waters can enter a few structures, especially in usually 
      vulnerable spots. A few places where rapid ponding of water 
      occurs at underpasses, low-lying spots, and poor drainage 
      areas. Several storm drains and retention ponds become 
      near-full and begin to overflow. Some brief road and bridge 
      closures. 

PRECAUTIONARY/PREPAREDNESS ACTIONS
