Tropical Depression Harvey has not moved much today but is expected
to strengthen as it moves NW towards the Texas Coast. TD Harvey is
expected to continue to strengthen into a tropical storm or hurricane
during the next couple of days. The primary impact from Harvey remains
heavy rainfall and subsequent flooding, but there will still be a
threat for tropical storm to hurricane force winds and storm surge
along the coast. The most likely arrival time for Tropical Storm force
winds to reach the Upper Texas Coast is during the day on Friday.
Harvey is forecast to remain somewhere in the vicinity of S to SE Texas
through the weekend and will continue to pose a heavy rainfall and
flooding threat into early next week. Coastal flooding will likely be
an ongoing issue Friday through the weekend as tides will remain


    Prepare for life-threatening rainfall flooding having possible
    extensive impacts across Southeast Texas. Potential
    impacts include:
  • Major rainfall flooding may prompt many evacuations and rescues.
  • Rivers and tributaries may rapidly overflow their banks in
    multiple places. Small streams, creeks, canals, and ditches may
    become dangerous rivers. Flood control systems and barriers
    may become stressed.
  • Flood waters can enter many structures within multiple
    communities, some structures becoming uninhabitable or washed
    away. Many places where flood waters may cover escape routes.
    Streets and parking lots become rivers of moving water with
    underpasses submerged. Driving conditions become dangerous.
    Many road and bridge closures with some weakened or washed out.
  • SURGE:
    Prepare for life-threatening surge having possible significant
    impacts across the Upper Texas Coast. Potential impacts in
    this area include:

  • Areas of inundation with storm surge flooding accentuated by
    waves. Damage to several buildings, mainly near the coast.
  • Sections of near-shore escape routes and secondary roads become
    weakened or washed out, especially in usually vulnerable low
  • Major beach erosion with heavy surf breaching dunes. Strong and
    numerous rip currents.
  • Moderate damage to marinas, docks, boardwalks, and piers.
    Several small craft broken away from moorings, especially in
    unprotected anchorages.
  • Also, prepare for locally hazardous surge having possible limited
    impacts across northern Galveston Bay and Trinity Bay.

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

    • WIND:
      Prepare for dangerous wind having possible significant impacts across
      the Upper Texas Coast, primarily near Matagorda Bay. Potential impacts
      in this area include:
    • 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. Several
      fences and roadway signs blown over.
    • Some roads impassable from large debris, and more within urban
      or heavily wooded places. A few bridges, causeways, and access
      routes impassable.
    • Scattered power and communications outages, but more prevalent
      in areas with above ground lines.
    Prepare for a tornado event having possible limited impacts across
    Southeast Texas. Potential impacts include:

  • The occurrence of isolated tornadoes can hinder the execution
    of emergency plans during tropical events.
  • A few places may experience tornado damage, along with power
    and communications disruptions.
  • Locations could realize roofs peeled off buildings, chimneys
    toppled, mobile homes pushed off foundations or overturned,
    large tree tops and branches snapped off, shallow-rooted trees
    knocked over, moving vehicles blown off roads, and small boats
    pulled from moorings.


    If you are exceptionally vulnerable to wind or water hazards from
    tropical systems, consider voluntary evacuation, especially if being
    officially recommended. Relocate to a predetermined shelter or safe

    If evacuating away from the area or relocating to a nearby shelter,
    leave early before weather conditions become hazardous.

      Now is the time to check your emergency plan and take necessary
      actions to secure your home or business. Deliberate efforts should be
      underway to protect life and property. Ensure that your Emergency
      Supplies Kit is stocked and ready.

    When making safety and preparedness decisions, do not focus on the
    exact forecast track as there are inherent forecast uncertainties
    which must be taken into account.

    If you live in a place that is particularly vulnerable to high wind,
    such as a mobile home, an upper floor of a high rise building, or on
    a boat, plan to move to safe shelter. Take enough supplies for you
    and your family for several days.

    If you live in a place particularly vulnerable to flooding, such as
    near the ocean or a large inland lake, in a low lying or poor
    drainage area, in a valley or canyon, or near an already swollen
    river, plan to move to safe shelter on higher ground

    Always heed the advice of local officials and comply with any orders
    that are issued. Do not needlessly jeopardize your life or the lives
    of others.

    When securing your property, outside preparations should be conducted
    as soon as possible before conditions deteriorate. The onset of
    strong gusty winds and heavy rain can cause certain preparedness
    activities to become unsafe.

    Be sure to let friends and other family members know of your
    intentions and whereabouts for surviving the storm. For emergency
    purposes, have someone located away from the threatened area serve as
    your point of contact. Share vital contact information with others.
    Keep cell phones handy and well charged.

    Be a Good Samaritan and check on those who may not be fully aware of
    the situation or who are unable to make personal preparations.

    Visitors to the area should become familiar with nearby surroundings.
    If you are a visitor, know the name of the county or parish in which
    you are located and where it is relative to current watches and
    warnings. If staying at a hotel, ask the management staff about their
    onsite disaster plan. Listen for evacuation orders, especially
    pertaining to area visitors.

    Closely monitor NOAA Weather Radio or other local news outlets for
    official storm information. Listen for possible changes to the
