Potential Tropical Cyclone Five is expected to bring tropical storm conditions to portions of the Upper Texas and southwestern Louisiana coasts on Tuesday.
A Tropical Storm Warning is in effect from Port Bolivar, Texas, to the Vermilion/Cameron Parish Line, Louisiana. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, in this case within the next 24-36 hours.
Potential Tropical Cyclone (PTC) Five is currently about 130 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 or so, 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
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.

Tropical Storm Outlook
An area of low pressure located a little more than 100 miles south of the coast of southern Louisiana continues to produce a small but concentrated area of showers and thunderstorms with some signs of organization. Additional development is expected as the low moves slowly west-northwestward, and a short-lived tropical depression or tropical storm is likely to form before the system reaches the Upper Texas or southwestern Louisiana coasts on Tuesday.
Interests along the southwestern Louisiana and Upper Texas coasts should monitor the progress of this system, as tropical storm watches or warnings could be required for portions of the area later today. Regardless of development, this system is expected to bring locally heavy rainfall to portions of the Upper Texas and southwestern Louisiana coasts during the next couple of days. An Air Force Reserve reconnaissance aircraft is scheduled to investigate the system this morning. Additional information on this system, including gale warnings, can be found in High Seas Forecasts issued by the National Weather Service. It has a high (70%) chance of formation in 48 hours and in the next seven days.
