Harvey remains a Category 1 hurricane on the Saffir-Simpson wind
scale. Though wind speeds have been slowly decreasing, heavy rainfall
will continue, and is the primary threat to Southeast Texas. Flash
flood warnings are already in effect across large portions of the
area, and extreme widespread flooding is possible at least into the
early week. Tornadoes have also occurred in the area overnight, and
will continue to be a threat today. Coastal flooding can be expected
at the shore where winds will continue to push water onshore. Tropical
storm force winds are possible today mainly in the southwestern
portions of the area towards Matagorda Bay. Storm surge will be slow
to recede through Sunday, particularly west of Freeport. Elevated tide
levels are expected through Tuesday. Though there are multiple hazards
occurring in the area, the greatest threat to life and property in the
coming days are tied to the potential for extreme rainfall amounts.
This rain will lead to a prolonged, dangerous, and potentially
catastrophic flooding event well into next week.
* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
Southeast Texas. Remain well guarded against life-threatening flood
waters having possible catastrophic impacts. If
realized, these impacts include:
– Extreme rainfall flooding may prompt numerous evacuations and
– Rivers and tributaries may overwhelmingly overflow their banks
in many places with deep moving water. Small streams, creeks,
canals, and ditches may become raging rivers. Flood control
systems and barriers may become stressed.
– Flood waters can enter numerous structures within multiple
communities, some structures becoming uninhabitable or washed
away. Numerous places where flood waters may cover escape
routes. Streets and parking lots become rivers of raging water
with underpasses submerged. Driving conditions become very
dangerous. Numerous road and bridge closures with some weakened
or washed out.
Potential impacts from the main wind event are now unfolding across
the Matagorda Bay area. Remain well sheltered from
life-threatening wind having possible extensive
impacts. If realized, these impacts include:
– Considerable roof damage to sturdy buildings, with some having
window, door, and garage door failures leading to structural
damage. Mobile homes severely damaged, with some destroyed.
Damage accentuated by airborne projectiles. Locations may be
uninhabitable for weeks.
– Many large trees snapped or uprooted along with fences and
roadway signs blown over.
– Some roads impassable from large debris, and more within urban
or heavily wooded places. Several bridges, causeways, and
access routes impassable.
– Large areas with power and communications outages.
Potential impacts from the main wind event are also now unfolding
across the southwestern portion of Southeast Texas. Remain well
sheltered from dangerous wind having possible limited to
Potential impacts from the main surge event are now unfolding across
the Upper Texas Coast, primarily west of Sargent. Remain well away
from life-threatening surge having possible significant impacts. If
realized, these impacts 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
Potential impacts from the main surge event are also now unfolding
across the Upper Texas Coast east of Sargent. Remain well away from locally
hazardous surge having possible limited impacts.
Potential impacts from tornadoes are still unfolding across Southeast
Texas, particularly within a couple counties of the coast. Remain well
braced against a tornado event having additional limited impacts. If
realized, these 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.
Do not return to evacuated areas until hazardous winds diminish
and flood waters abate.
* OTHER PREPAREDNESS INFORMATION:
Now is the time to remain safely sheltered from the storm. Stay
inside and away from windows. Listen for updates and be ready in case
you lose electrical power. Locate your battery powered radio and
flashlight from your Emergency Supplies Kit. Keep these items close.
During the peak of the storm, keep your shoes on and rain gear handy.
Boots and tennis shoes offer the best foot protection if you become
unexpectedly exposed to the elements.
Continue to keep your cell phone well charged for as long as
possible. If you lose power, use it more sparingly and mainly for
personal emergencies and check-ins. Do not overload communications
systems with idle chatter.
Do not be a thrill seeker or risk your life for senseless photos or
videos. Be wise and avoid becoming another statistic.
Be ready to move to the identified safe room if you are within a tornado
warning. Quickly move to an interior room on the lowest floor.
Put as many sturdy walls between you and the storm as you can.
Protect your head and body.
