Nicholas strengthened into a Category 1 hurricane Monday as it headed toward landfall along the Texas Gulf Coast and it was expected to bring heavy rain and floods to coastal areas from Mexico to storm-battered Louisiana.
Forecasters at the National Hurricane Center in Miami said top sustained winds reached 75 mph (120 kph) a few hours before expected landfall.
Although the system was expected to generate only a fraction as much rain as Harvey, a hurricane warning was issued for Port O’Connor to Freeport, as well as a hurricane watch from Freeport to the western tip of Galveston Island. A tropical storm warning was issued for Port Aransas to Sabine Pass, as well as a storm surge warning for Port Aransas to Sabine Pass, including Galveston, Aransas, San Antonio and Matagorda bays. A storm surge watch is in effect from Sabine Pass to Rutherford Beach, Louisiana.
An automated station in Matagorda Bay registered a sustained wind of 76 mph (122 kph) with gusts to 95 mph (153 kph), the hurricane center reported. About 50,000 customers were without power in Texas on Monday night, according to the utility tracking site poweroutage.us.
In flood-prone Houston, officials worried that heavy rain expected to arrive late Monday and early Tuesday could inundate streets and flood homes. Authorities deployed high-water rescue vehicles throughout the city and erected barricades at more than 40 locations that tend to flood, Mayor Sylvester Turner said.
“This city is very resilient. We know what we need to do. We know about preparing,” said Turner, referencing four major flood events that have hit the Houston area in recent years, including devastating damage from Harvey, which flooded more than 150,000 homes in the Houston area.
