POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
Prepare for life-threatening rainfall flooding having possible
extensive impacts across portions of southeast Texas. Potential
impacts include:
- Major rainfall flooding may prompt many 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.
Prepare for dangerous rainfall flooding having possible limited to
significant impacts across southeast Texas.
* WIND:
Prepare for hazardous wind having possible limited impacts across
the coastal portions of southeast Texas. Potential impacts in
this area include:
- 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.
- Scattered power and communications outages.
Elsewhere across Southeast Texas, little to no impact is anticipated.
* SURGE:
Coastal flood warnings and advisories have been issued for the
immediate coast. Please reference the Coastal Hazard Message for
more information. Potential impacts in this area include:
- Numerous roads may be closed. Low lying property
including homes, businesses, and some critical infrastructure
could be inundated. Some shoreline erosion will occur.
* TORNADOES:
Prepare for a tornado event having possible limited impacts
across southeast Texas. Potential impacts include:
- The occurrence of isolated tornadoes can hinder the ex*****on
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.
Elsewhere across Southeast Texas, little to no impact is anticipated.
