At 7 PM CDT, the center of Tropical Depression Harvey was located at 21.7 N and 92.5 W with a northwestward motion at 2 mph. A track toward the northwest or north-northwest is expected for the next 48 hours. On the forecast track, Harvey should be approaching the Texas coast late Friday. Maximum sustained winds are near 35 mph with higher gusts. Some strengthening is forecast during the next 48 hours, and Harvey could become a hurricane on Friday prior to landfall. Potential impacts to the lower Texas coast and the coastal portions of Kenedy, Willacy and Cameron counties include dangerous marine conditions, coastal flooding, beach erosion and rainfall; which may be heavy at times, especially towards coastal counties. Water may pond on roadways and some flooding may occur in low-lying or poorly-draining areas, especially towards the coast and South Padre Island. Stay tuned to weather.gov/rgv for future updates and follow the latest at hurricanes.gov!
A Hurricane Watch is in effect for coastal portions of Kenedy county as well as adjacent coastal, nearshore and offshore waters out 60 nautical miles east of Padre Island. A Tropical Storm Watch is in effect for coastal portions of Willacy and Cameron counties, as well as adjacent coastal, nearshore and offshore waters out 60 Nautical miles east of Padre Island. A Storm Surge Watch is in effect for portions of South Padre Island in Willacy county. Most impacts will be along the coast and a few miles inland from the coast. Rain may be heavy at times.
Partly cloudy skies are expected tonight across deep south Texas with overnight temperatures falling into the middle to upper 70s. Isolated showers and thunderstorms will be possible along the coast and across the gulf waters during the night. For the mariners, expect east to east-northeast winds with a light chop across the Laguna Madre and seas across the coastal gulf waters of 2 to 4 feet. Tropical Storm, Hurricane and Storm Surge Watches are in effect along the coast and across the coastal gulf waters out advance of Harvey.
Isolated showers and thunderstorms are possible along the sea breeze during the day Thursday. As the tropical disturbance in the Gulf moves closer, the chance of showers and thunderstorms will increase, especially towards the coastal counties Thursday evening into Friday. The increased moisture off of the Gulf will continue higher chances of rain through the weekend, with more sea breeze activity set to resume on Monday. Low temperatures are expected to be at or even slightly below normal through the weekend in the low to mid 70s for most. Afternoon high temperatures catch a small break with the increased cloud cover and rain, dipping below normal on Friday before settling towards normal into next week.
