As anticipated, Tropical Storm Nicholas formed earlier today. As of late Sunday evening, Nicholas was 260 miles south-southeast of the mouth of the Rio Grande River. Nicholas was drifting to the north at 2 mph. Maximum sustained winds are 35 mph.

Nicholas is expected to intensify as it parallels and gradually moves towards the middle Gulf Coast. Expect landfall on Tuesday morning along the middle TX coast. Given how closely Nicolas is paralleling the coast, a slight chance in forecast track could move landfall anywhere between Corpus Christi and Galveston Bay.

The primary impact from Nicholas will be extensive rains. Coastal areas from Corpus Christi to Beaumont should prepare for up to a foot of rain from this storm. This will cause extensive flooding. The middle TX coast should expect a 3-5 foot storm surge; both Corpus Christi and Galveston Bays will likely have 2-4 feet of storm surge. Winds on the eastern side of Nicholas could be approaching hurricane force, but most on the TX coast will see tropical storm force winds of 30-60 mph.

If I was camping or planning an RV trip along the TX coast anywhere north of Corpus Christi for next week I would reschedule my trip if at all possible. If I’m already on the coast I would spend Monday ensuring my rig is ready to roll with full fuel, fresh water and propane, and empty waste tanks. Seek higher ground from both storm surge and freshwater flooding, and, as always, please follow the advice of local emergency management officials.
