Potential Severe Weather
Tropical Storm Nicholas
US Coast Guard Sector Corpus Christi held a Port Coordination Team (PCT) conference call at 0930 hours today, to alert the industry of possible heavy weather impact to the South Texas coast due to Tropical Storm Nicholas. Your WGMA Maritime Affairs team participated on the call and has the following report:

At 12 PM today, US Coast Guard Sector Corpus Christi will set Port Condition YANKEE for selected areas of Sector Corpus Christi. The area placed under Port Condition YANKEE will be north of Rockport to the Colorado River Locks. Areas south of Rockport shall remain at Port Condition X-RAY. Once Port Condition YANKEE is set, all vessel movements within that area will require approval of the Captain of the Port. They are closely monitoring the storm. At this time, there is no expectation of setting Port Condition ZULU.

National Weather Service Marine Forecast for Corpus Christi:
Tropical Storm Nicholas has slowed considerably overnight, running parallel offshore. The expected landfall of the storm will be near Port O’Connor later this evening. Wave heights were being reported at 13 feet this morning. This evening, waves of 15-20 feet and possibly 25 feet are expected offshore. Winds are forecast to be 50-60 miles per hour sustained, with gusts of hurricane force. Rainfall amounts of 4-10 inches are anticipated across the region. A Flash Flood Watch was issued for the Coastal Bend. A storm surge of 2-4 feet is anticipated.

From National Hurricane Center:
At 7AM CDT, the center of Tropical Storm Nicholas was located near latitude 25.4 North, longitude 96.9 West. Nicholas has been drifting toward the north-northwest near 5 mph. The storm should move northward later today at a faster forward speed, and turn north-northeastward on Tuesday. On the forecast track, the center of Nicholas will pass near or just offshore the coasts of northeastern Mexico and south Texas this morning, and move onshore along the coast of the south or central Texas late this afternoon or evening. Maximum sustained winds are near 60 mph with higher gusts. Strengthening is forecast today, and Nicholas could reach the northwest Gulf coast as a hurricane. Weakening is anticipated on Tuesday and Wednesday while Nicholas moves over land. Tropical-storm-force winds extend outward up to 115 miles (185 km) from the center. A Weatherflow station on South Padre Island, Texas, recently reported a wind gust to 45 mph.
