Tropical Storm Marco Update: Saturday Update

Good Saturday morning! Here is your midday look at what has now become Tropical Storm Marco. 

The National Hurricane Center is forecasting Marco to strengthen into a hurricane as it moves into the southeastern Gulf of Mexico by tonight. 

From there, they expect Marco to move across the central Gulf of Mexico as a hurricane Sunday and approach the central Gulf Coast on Monday. 

Further East, Tropical Storm Laura is forecast to strengthen over the Gulf of Mexico by the middle of next week. The current forecast indicates Laura will move over the central Gulf of Mexico a day or two after Marco.

At 10 AM CDT, Marco was located at 20.9N 85.3W or 881 miles from Port Aransas, TX. Maximum Sustained Winds: 65 mph; Movement: NNW or 340 degrees at 12 mph.; Minimum Central Pressure: 992mb. 

You’ll notice that there was some intensification from last night and details on how Marco will impact Texas are still somewhat uncertain. That said, the National Weather Service is saying that Tropical storm force winds are possible Monday through Tuesday over the Coastal Waters. 

According to the official forecast, rainfall amounts of 1 to 2 inches will be possible for coastal counties. Lower amounts are expected farther inland.

They also say that you can expect high that usual tides beginning Monday night and continuing through Tuesday night. Minor coastal flooding and an increased risk of rip currents are possible. Wave heights are likely to increase Monday and Tuesday, potentially reaching 7 – 11 feet.

What Should You Do?

First things first, prepare. Go ahead and make sure that your supplies are topped off, make sure you have everything in a safe and dry place, and keep an eye on the weather for updates. 

The next update from NHC will be at 4PM. We will pass that along when it comes in.
