Nicholas reached hurricane strength at 03:00 UTC on September 14, 2021, and made landfall on the eastern part of the Matagorda Peninsula, about 15 km (10 miles) WSW of Sargent Beach, Texas at 05:30 UTC with maximum sustained winds of 120 km/h (75 mph) and a minimum central pressure of 991 hPa. The storm brought heavy rain, strong winds and dangerous storm surge.
Nicholas is moving toward the north-northeast near 17 km/h (10 miles) and this general motion is expected to continue through tonight (LT), followed by a turn toward the northeast and a slower motion by late Tuesday, September 14 and an even slower eastward motion on Wednesday, September 15.
On the forecast track, the center of Nicholas is expected to move slowly over southeastern Texas today and tonight, and over southwestern Louisiana on Wednesday.1
Heavy rainfall will impact portions of southeastern Texas, Louisiana, and southern Mississippi through the middle of the week, NHC forecaster Pasch noted.2
Significant rainfall amounts are expected, potentially resulting in areas of life-threatening flash and urban flooding, along the eastern Texas coast into southwestern Louisiana.
Minor to isolated major river flooding is also possible in smaller river basins and urban areas.
