SUMMARY OF 100 AM CDT...0600 UTC...INFORMATION ---------------------------------------------- LOCATION...25.9N 88.8W ABOUT 500 MI...800 KM ESE OF PORT OCONNOR TEXAS MAXIMUM SUSTAINED WINDS...30 MPH...45 KM/H PRESENT MOVEMENT...WNW OR 285 DEGREES AT 6 MPH...9 KM/H MINIMUM CENTRAL PRESSURE...1009 MB...29.80 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: None. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Watch is in effect for... * Port Mansfield to High Island Texas A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Interests elsewhere along the Texas and Louisiana coast should monitor the progress of this system. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND OUTLOOK ---------------------- At 100 AM CDT (0600 UTC), the center of Tropical Depression Eight was located near latitude 25.9 North, longitude 88.8 West. The depression is moving toward the west-northwest near 6 mph, and this general motion is expected during the next few days. On the forecast track, the center of the depression is expected to move across the northwestern Gulf of Mexico today and Friday and make landfall along the Texas coast on Saturday. Maximum sustained winds are near 30 mph (45 km/h) with higher gusts. Slow strengthening is expected, and the depression could become a tropical storm in a day or so. The estimated minimum central pressure is 1009 mb (29.80 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are possible within the watch area by late Friday. RAINFALL: The depression is expected to produce 2 to 4 inches of rain with isolated maximum totals of 6 inches along the Gulf coast from Louisiana to the Lower Texas coast, and inland through south-central Texas and the Rio Grande Valley. SURF: Swells generated by the depression are expected to increase and affect much of the Texas and Louisiana coasts in a day or two. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 400 AM CDT. $$ Forecaster Pasch

Tropical Depression Eight Forecast Discussion Number 1
2020-07-23 04:42:45| National Hurricane Center (Atlantic)
Issued at 1000 PM CDT Wed Jul 22 2020 000 WTNT43 KNHC 230242 TCDAT3 Tropical Depression Eight Discussion Number 1 NWS National Hurricane Center Miami FL AL082020 1000 PM CDT Wed Jul 22 2020 Surface observations and data from the Air Force Hurricane Hunters indicate that the area of low pressure over the central Gulf of Mexico has developed a closed circulation and a well-defined center. In addition, recent satellite images show an area of deep convection expanding over the center. Based on those observations, advisories are being initiated on Tropical Depression Eight. The initial intensity is set at 25 kt based on the earlier reconnaissance data. The initial motion is an uncertain west-northwestward at 5 kt. A subtropical ridge to the northeast of the depression should cause it to continue moving in that general direction through Friday as it tracks across the northwestern Gulf of Mexico. A slight turn to the left is expected Friday night and Saturday as a ridge builds to the north of the system, taking the center of cyclone across the Texas coast and then inland over southern Texas. The models are in fairly good agreement on this scenario, and the NHC track forecast lies near the various consensus models. The depression is expected to be in generally light to moderate wind shear conditions, in a fairly moist environment, and over the warm waters of the Gulf of Mexico for the next couple of days, so some strengthening seems likely. However, since the depression is still in its formative stage, the rate of strengthening should be gradual. After the storm crosses the coast, steady weakening should commence. The NHC intensity forecast generally follows the IVCN and HCCA guidance. Key Messages 1. The depression is expected to strengthen and it could bring tropical-storm-force winds to portions of the Texas coast, where a tropical storm watch has been issued. 2. The depression is expected to produce heavy rains across portions of Louisiana and southern Texas. These rains could result in flash flooding.
