    leave if evacuation orders are given for your area.

    - POTENTIAL IMPACTS: Limited
    - 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

    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.

    * 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: Plans should still include the potential for a few
    tornadoes.

    Flood Watch - 1:10am Wed Jun 17 2026

    ...FLOOD WATCH NOW IN EFFECT THROUGH THIS EVENING...

    WHAT: Flooding caused by excessive rainfall continues to be
    possible.

    WHERE: Portions of south central and southeast Texas, including
    the following areas, in south central Texas, Coastal Jackson and
    Inland Jackson. In southeast Texas, Bolivar Peninsula, Brazoria
    Islands, Chambers, Coastal Brazoria, Coastal Galveston, Coastal
    Harris, Coastal Matagorda, Fort Bend, Galveston Island, Inland
    Brazoria, Inland Galveston, Inland Harris, Inland Matagorda,
    Matagorda Islands, Montgomery, Northern Liberty, Southern Liberty
    and Wharton.

    WHEN: Through this evening.

    IMPACTS: Excessive runoff may result in flooding of rivers,
    creeks, streams, and other low-lying and flood-prone locations.
    Extensive street flooding and flooding of creeks and rivers are
    possible.

    ADDITIONAL DETAILS: - Coastal areas will have the greatest potential for flooding
    through this afternoon as Potential Tropical Cyclone One
    skirts along the Upper Texas Coast. Rainfall rates could
    exceed 4 inches per hour in the heaviest downpours.
    Additional widespread rainfall amounts of 2 to 4 inches in
    the watch area with isolated higher totals possible
    especially along the coast. Grounds are fairly saturated
    across portions of Southeast Texas, which would allow for a
    quicker transition of the rainfall to runoff. This increases
    the potential for flooding, especially in the areas that have
    received 4+ inches of rain over the past few days.

    - Http://www.weather.gov/safety/flood

    PRECAUTIONARY / PREPAREDNESS ACTIONS:

    You should monitor later forecasts and be alert for possible Flood
    Warnings. Those living in areas prone to flooding should be prepared
    to take action should flooding develop.
