PTC Five nears Gulf

The National Hurricane Center has designated Potential Tropical Cyclone Five as it takes shape in the northern Gulf, with the system forecast to become Tropical Storm Edouard later in the day Monday and then move inland near the Texas-Louisiana border on Tuesday.

Potential Tropical Cyclone (PTC) 5 was announced at 11 a.m. Monday

WPTV reported that Potential Tropical Cyclone (PTC) 5 was announced at 11 a.m. Monday and that the NHC gives the system an 80% chance of development as it drifts westward, while the system currently lacks a closed center of circulation.

The Weather Channel said the NHC is monitoring an area of low pressure in the northern Gulf a little more than 100 miles off the coast of Louisiana, moving west-northwest, with thunderstorms becoming increasingly clustered and wind shear fairly light.

ABC News said the developing system could become a tropical storm and make landfall in Texas near the Louisiana border on Tuesday morning, and it cited a 70% chance of tropical formation.

WWSB reported that the NHC designated the disturbance Potential Tropical Cyclone Five as it gradually becomes better organized, noting it does not yet have a well-defined center but that Gulf waters are extremely warm and upper-level winds are relatively light.

Warnings, rain totals, winds

A tropical storm warning extends along the northwestern Gulf Coast from Port Bolivar, Texas, to the Vermilion/Cameron Parish line in Louisiana, and FOX Weather said the system has prompted the warning with maximum sustained winds of 35 mph.

Houston Public Media reported that NWS predicted rainfall rates exceeding 3-4 inches per hour during the heaviest downpours, with isolated areas potentially reaching 6-9 inches, and it said Houston could see up to 3 inches and Galveston up to 4 inches.

The Weather Channel said flooding rain is possible in Houston and across eastern Texas and southwest Louisiana, and it described a flood watch for southeast Texas, including Houston, through Wednesday morning.

ABC News said towns including Liberty could see more than half a foot of rain on Tuesday alone, along with strong wind gusts around 40 or 50 mph.

CW39 Houston said the system is expected to approach Texas by Tuesday, with heavy rain, gusty winds, and possible waterspout or isolated tornado as it pushes inland through the day.

Edouard name, short-lived risk

Multiple outlets tied the next storm name to the system’s potential development, with WPTV saying that if it strengthens into a named storm, it would be called Edouard and with ABC News saying it may strengthen to Tropical Storm Edouard and make landfall near the Louisiana border on Tuesday morning.

El Comercio Perú said Invest 97L has 70% possibilities of becoming a depression tropical or storm during the next 48 hours, and it described the system as about 125 millas al sur de la costa sureste de Luisiana moving slowly in direction oeste-noroeste.

Eye on the Tropics said the next name on the list is Edouard and described Invest 97L as expected to be weak and short-lived, with forecast models keeping it weak (low to mid-tier tropical storm at most) over the next 24 hours before it moves inland over the Upper Texas Coast.

The Weather Channel warned that a one to three foot storm surge is also possible on the Texas and Louisiana coastlines, while it said generally 3-6 inches of rainfall is expected and up to 9 inches are possible on the upper Texas Coast.

WPTV also said the remnants of Tropical Storm Dolly continue to bring heavy rain and gusty winds near Puerto Rico and the Virgin Islands, and it reported the NHC gives Dolly’s remnants a 10% chance of redevelopment over the next seven days.
