Tropical Storm Nicholas to hit Texas coastlines tonight and Monday; 3 other disturbances move in the Atlantic

Tropical Storm Nicholas is strengthening as it moves northeast in the Gulf of Mexico and up the Texas shoreline Monday morning.

Nicholas is about 200 miles south of Port O’Connor, Texas, and 45 miles southeast of the mouth of the Rio Grande. The system is now moving north at 2 mph with maximum sustained winds of 60 mph, according to the NHC’s 5 a.m. update.

Tropical storm warnings and watches remain in effect for territories going from the east coast of Mexico to the south coast of Texas.

Storm surge warnings and a hurricane watch were issued for Texas coastlines, including Freeport, San Luis Pass, Aransas Bay, San Antonio Bay, and Matagorda Bay.

“On the forecast track, the center of Nicholas will pass near or just offshore the coasts of northeastern Mexico and South Texas on Monday, and move onshore along the coast of south or central Texas coast Monday night or early Tuesday,” NHC specialist Richard Pasch.

The NHC is monitoring three other tropical disturbances in the Atlantic that have a chance to become a depression or storm.

There could be a gradual development where the waves transform to a tropical depression early next week as they move west over the Atlantic, according to the NHC.

The closest one to Florida is a low that is expected to form near the southeastern Bahamas in the next few days with a 50% chance of formation by next week. Gradual development is possible as it moves northwest across the Atlantic. It’s still unclear what impact if any it will have on the Sunshine State.

A tropical wave is expected to emerge off the west coast of Africa in the next few days and has a 20% chance of formation in the next 48 hours and a 70% chance of formation by next week.

Another wave causing disorganized showers and thunderstorms near the Cabo Verde Islands earlier today has now dissipated.

The last disturbance is located a few hundred miles east of the Azores, but there’s an unlikely chance of significant development with a low 10% chance of formation by next week.

If these systems form into tropical storms, they would be named Tropical Storm Odette, Tropical Storm Peter, and Tropical Storm Rose. The 2021 season has already seen 13 named systems including five hurricanes, three of which have been major hurricanes of Category 3 strength or higher.
