    - LATEST LOCAL FORECAST: Below tropical storm force wind
        - Peak Wind Forecast: 10-15 mph with gusts to 25 mph

    - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST
      UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for wind 39
      to 57 mph
        - The wind threat has remained nearly steady from the
          previous assessment.
        - PLAN: Plan for hazardous wind of equivalent tropical storm
          force.
        - PREPARE: Remaining efforts to protect property should be
          completed as soon as possible. Prepare for limited wind
          damage.
        - ACT: Move to safe shelter before the wind becomes hazardous.

    - POTENTIAL IMPACTS: Limited
        - Damage to porches, awnings, carports, sheds, and unanchored
          mobile homes. Unsecured lightweight objects blown about.
        - Large tree limbs broken off. A few trees snapped or
          uprooted, but with greater numbers in places where trees
          are shallow rooted.
        - Some roads impassable due to debris, particularly within
          urban or heavily wooded locations. Hazardous driving
          conditions on bridges and other elevated roadways,
          especially for high profile vehicles.
        - Isolated to scattered power and communications outages.

    - No storm surge inundation forecast

    - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST
      UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Little to no storm
      surge flooding
        - The storm surge threat has decreased from the previous

          waters recede.
        - PREPARE: Heed instructions from local officials when moving
          about. Do not enter flooded areas.
        - ACT: Exercise safety.

    - REALIZED IMPACTS: Being Assessed

          officials are now assessing the extent of actual surge
          impacts accordingly.

* FLOODING RAIN
    - LATEST LOCAL FORECAST:
        - Peak Rainfall Amounts: No additional significant rainfall
          forecast

      localized flooding rain
        - The flooding rain threat has remained nearly steady from
          the previous assessment.
        - PLAN: Emergency plans should include the potential for
          localized flooding from heavy rain.
        - PREPARE: Consider protective actions if you are in an area
          vulnerable to flooding.
        - ACT: Heed any flood watches and warnings.

    - POTENTIAL IMPACTS: Limited
        - Localized rainfall flooding could prompt a few rescues.
        - Rivers and tributaries could quickly rise with swifter
          currents. Small streams, creeks, canals, and ditches could
          become swollen and overflow in spots.
        - Flood waters can enter a few structures, especially in
          normally vulnerable spots. Rapid ponding of water could
          occur 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.

* TORNADO
    - LATEST LOCAL FORECAST:
        - Situation is somewhat favorable for tornadoes

    - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST
      UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for a few
      tornadoes
        - The tornado threat has remained nearly steady from the
          previous assessment.
        - PLAN: Emergency plans should include the potential for a
          few tornadoes.
        - PREPARE: If your shelter is particularly vulnerable to
          tornadoes, prepare to relocate to safe shelter before
          hazardous weather arrives.
        - ACT: If a tornado warning is issued, be ready to shelter
          quickly.

    - POTENTIAL IMPACTS: Limited
        - Isolated tornadoes can hinder the execution of emergency
          plans.
        - Isolated locations could experience tornado damage, along
          with power and communications disruptions.
        - In isolated locations, tornadoes could damage trees,
          vehicles, boats and buildings, especially mobile homes and
          other poorly constructed structures.
