    Tropical Weather Statement - 4:33pm Mon Aug 31 2026

    This product covers Southeast Texas

    **Tropical Depression Five to Bring Locally Heavy Rainfall for
    Portions of Southeast Texas**

    NEW INFORMATION ---------------

    * CHANGES TO WATCHES AND WARNINGS:
    - None

    * CURRENT WATCHES AND WARNINGS:
    - A Tropical Storm Warning is in effect for Bolivar Peninsula and
    Chambers

    * STORM INFORMATION:
    - About 210 miles east-southeast of Galveston TX
    - 28.2N 91.5W
    - Storm Intensity 35 mph
    - Movement West-northwest or 300 degrees at 6 mph

    SITUATION OVERVIEW ------------------

    Tropical Depression Five is currently about 105 miles south of the
    Louisiana coast, slowly moving west-northwestward towards the
    northwestern Gulf Coast. It is expected to become a Tropical Storm
    within the next 24 hours, before making landfall along the Upper Texas
    coast, somewhere within the Warning area. Periods of moderate to heavy
    rainfall associated are expected to begin as early as late tonight and
    lasting into late Tuesday night/early Wednesday morning. 3-5 inches of
    rain with isolated amounts of 6-9 inches are expected with the highest
    totals occuring east of I-45. Rainfall rates will exceed 3-4 inches
    per hour at times in the heaviest downpours, which can lead to flash
    flooding especially in urban and vulnerable areas.

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

    * FLOODING RAIN:
    Protect against dangerous rainfall flooding having possible
    significant impacts mainly for areas east of I-45. 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.

    Protect against locally hazardous rainfall flooding having possible
    limited impacts across the rest of Southeast Texas.

    * WIND:
    Protect against hazardous wind having possible limited impacts across
    Bolivar Peninsula and Chambers County
    . Potential impacts in this area 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.

    Elsewhere across Southeast Texas, little to no impact is anticipated.

    * SURGE:
    Protect against locally hazardous surge having possible limited
    impacts across Port Bolivar to High Island. Potential impacts in
    this area include:
    - Localized inundation with storm surge flooding mainly along
    immediate shorelines and in low-lying spots, or in areas
    farther inland near where higher surge waters move ashore.
    - Sections of near-shore roads and parking lots become overspread
    with surge water. Driving conditions dangerous in places where
    surge water covers the road.
    - Moderate beach erosion. Heavy surf also breaching dunes, mainly
    in usually vulnerable locations. Strong rip currents.
    - Minor to locally moderate damage to marinas, docks, boardwalks,
    and piers. A few small craft broken away from moorings.

    Elsewhere across Southeast Texas, little to no impact is anticipated.

    * TORNADOES:
    Little to no impacts are anticipated at this time
    across Southeast Texas.

    PRECAUTIONARY/PREPAREDNESS ACTIONS ----------------------------------

    * EVACUATIONS:
    Follow the advice of local officials.

    * OTHER PREPAREDNESS INFORMATION:
    Now is the time to complete all preparations to protect life and
    property in accordance with your emergency plan. Ensure you are in a
    safe location before the onset of strong winds or possible flooding.

    Keep cell phones well charged. Cell phone chargers for automobiles
    can be helpful, but be aware of your risk for deadly carbon monoxide
    poisoning if your car is left idling in a garage or other poorly
    ventilated area.

    If you are a visitor, be sure to know the name of the city or town in
    which you are staying and the name of the county or parish in which
    it resides. Listen for these locations in local news updates. Pay
    attention for instructions from local authorities.

    Closely monitor weather.gov, NOAA Weather radio or local news outlets
    for official storm information. Be ready to adapt to possible changes
    to the forecast. Ensure you have multiple ways to receive weather
    warnings.
