GMZ300 Synopsis For High Island To The Matagorda Ship Channel Out 60 Nautical Miles Including Galveston And Matagorda Bays 1008 Am Cdt Tue Jun 18 2024

Synopsis for high island to the matagorda ship channel out 60 nm including galveston and matagorda bays
a broad area of low pressure over the southwestern gulf of mexico is expected to become a tropical storm as it tracks towards mexico. Highs winds, hazardous seas, and above normal coastal water levels are likely well north of the center of the storm. With the exception of galveston bay, a tropical storm warning is in effect over our coastal waters. Small craft advisory remains in effect for galveston bay, but some gusts above 35 knots are possible at times. Water levels will be rising and would anticipate some coastal flooding in the bays and along the beaches. Higher winds are possible in Thunderstorms. Small craft should consider remaining in port until weather conditions start improving later this week.

SYNOPSIS
Issued at 424 AM CDT Tue Jun 18 2024

Potential Tropical Cyclone One will bring a variety of hazards to our area over the next few days. Below is a list of primary concerns.

1) Heavy Rainfall

Periods of moderate to heavy rainfall are likely this evening through Wednesday, especially over our southern and coastal counties. The best chance of heavy rainfall capable of flash flooding will be from I-10 points south to the coast. If you encounter water covered roads while driving, please turn your car around. Have multiple ways to receive weather updates and warnings.

2) Hazardous Marine Conditions

Strong winds and rough seas are likely for the bays and Gulf waters through Thursday. Sustained winds up to 35 knots with gusts over 40 knots expected in the Gulf waters. Offshore seas of 10-15 feet are likely. Higher winds likely within and near thunderstorms.

3) Rough Surf / Coastal Flooding

Saltwater inundation of low-lying roads, property, and businesses during high tide is possible, especially on Wednesday. High water levels may disrupt ferry services. Rough surf and strong rip currents will result in conditions too dangerous for swimming.

4) Strong Winds

Winds near the coast could gust over 40 MPH at times today and tomorrow, with stronger gusts possible within thunderstorms.
Isolated damaging gusts associated with thunderstorms possible.
Inland winds gusts up to 25-30 MPH could result in hazardous driving for high profile vehicles.

SHORT TERM
(Today through Wednesday Night)
Issued at 205 AM CDT Tue Jun 18 2024

Deep tropical moisture will continue to pool into southeast Texas thanks to the slowly organizing tropical disturbance in the southwest Gulf of Mexico and the persistent LL high pressure system over eastern CONUS. Though development into a tropical storm appears likely, it is worth emphasizing the system's impacts will not be dependent on whether or not it develops. Strong coastal winds, high coastal water levels, and periods of heavy rainfall will be a concern regardless. As the system moves towards towards Mexico, deep LL onshore flow will send PWATs well over 2 inches with coastal PWATs possibly approaching 3 inches by this evening. The coverage of rainbands will gradually increase on the north side of the disturbance, extending well north of the center of circulation. Though isolated to scattered shower and thunderstorm activity is expected this morning and afternoon, the bulk of these rainbands are expected to remain offshore. By late this afternoon/evening and especially by tonight, these bands of showers and thunderstorms should be moving into SE Texas from the Gulf. The Weather Prediction Center (WPC) has kept our southern/coastal counties (including the City of Houston) in a Moderate (Level 3 of 4) risk of excessive rainfall capable of flash flooding for the Tuesday night to Wednesday time period.

So how much rainfall will occur? HRRR ensembles strongly suggest the presence of training rainbands that drop 5-10 inches of rain over the effected area. But where will those rainbands occur? Areas south of I-10, and particularly areas near the coast, appear to have the highest chance of seeing totals this heavy. HRRR ensemble maxima suggest the potential for locally over 10 inches of rainfall. But the overall total QPF forecast trend has been downward. Both hi-res and global guidance have been trending southward with the heaviest rainfall. These trends have resulted in a significant reduction in the expected rainfall over our northern counties. Expected totals from the Brazos Valley to Montgomery County have fallen to 1-2 inches while our northern Piney Woods counties have fallen under an inch. We still cannot rule out one of the aforementioned training rainbands impacting some of our northern counties. For that reason, WPC has our northern CWA in a Marginal (Level 1 of 4) to Slight (level 2 of 4)
excessive rainfall risk. Once you get south of I-10, rainfall totals are expected to average 3-6 inches, with higher totals likely in locations impacted by training rainbands. HRRR guidance is most aggressive with potential training bands in our SW counties from Brazoria and Fort Bend down to Matagorda Bay.
Locations not impacted by training rainbands will likely receive manageable rainfall. Most of the flash flooding should be associated with these bands.

The steeping LL gradient will also enhance winds today and tomorrow. Winds inland could easily gust over 25 MPH and possible over 30 MPH near and to the south of I-10. Closer to the coast, winds are expected to gust around 40 MPH. In addition, winds in the 925-850MB layer are expected to increase to 45 to 60 MPH. Any thunderstorm embedded within the rainbands will be capable of mixing some of the winds down to the surface, especially near the coast. Therefore, isolated damaging wind gusts cannot be ruled out. The long fetch of winds across the Gulf will also push the ocean waters towards the shore, enhancing water levels along the coast. Minor coastal flooding is possible during high tide today.
The highest levels are expected to occur during high tide on Wednesday, when there is a greater chance of saltwater inundation of low lying roads, property, and businesses. Water levels may become high enough to disrupt ferry services.

By Wednesday evening / night, the bulk of the rain and thunderstorms should pull west of our CWA However, gusty coastal winds and coastal flooding are likely to continue.

LONG TERM
(Thursday through Monday)
Issued at 205 AM CDT Tue Jun 18 2024

Things will begin settling down on Thursday as the current troffiness, and whatever becomes of the PTC, across the western Gulf transitions further inland into Mexico. Ridging over the eastern parts of the country begins to expand westward into Texas. Moisture levels will be trending down, but by down I mean PW's falling into the 1.75-2" range. This will still be ample enough for scattered, mainly diurnally driven, precip across southern parts of the CWA where a prevailing llvl easterly flow continues and less subsidence from ridging will be situated. Same type situation exists Friday.

Sat-Sun should be even a touch drier/warmer with broad, flat ridging stretching across most of the area. Mainly isolated activity expected near the coast/offshore. Late in the weekend into early next week, we'll have to turn our attention back toward the Gulf.
Could see another easterly wave make its way across the Yucatan. By early next week it should be positioned in somewhat of a weakness between mid/upper ridging to our west and east. 47

AVIATION
(12Z TAF Issuance)
Issued at 611 AM CDT Tue Jun 18 2024

VFR conditions will prevail through the first half of today, but increasing tropical moisture will cause increase cloud cover and showers/storms beginning this afternoon and continuing through Wednesday. Scattered showers will develop as early as 17z with some isolated thunderstorms possible, mainly south of IAH. There will be a lull in the thunderstorm activity during the late afternoon/evening, but widespread moderate to heavy showers with embedded thunderstorms will slide into SE Texas from the coast during the overnight hours tonight continuing into the day on Wednesday. MVFR conditions are expected to prevail beginning late this evening with CIGs down to 1500-2500ft. Gusty winds up to around 20-25kt inland, and up to 30-35kt along the coast (impacting mostly GLS) will begin to pick up this afternoon and continue through Wednesday.

MARINE
Issued at 205 AM CDT Tue Jun 18 2024

Hazardous winds and seas as well as well above normal water levels are likely to continue through Thursday. Sustained winds 25-35 knots with gusts potentially over 40 knots are likely today and tomorrow, along with offshore seas of 10-15 feet. Occasionally higher seas are likely. In addition, heavy bands of showers and thunderstorms are likely later today through Wednesday. Locally much strong winds are likely within and near thunderstorms.
Coastal flooding is likely during high tide today, Wednesday, and Thursday. Water levels could reach 4-6 feet above MLLW during high tide on Wednesday. Although conditions should begin to improve on Thursday, winds and seas of at least Small Craft Advisory level could linger until week's end.
