Nicholas formed on September 12 in the Southwestern Gulf of Mexico, slowly advancing northeastward along the Middle Texas Coast. It eventually made landfall 10 miles west of Sargent just after midnight on September 14, with maximum sustained wind speeds of 75 mph.

Additionally, Nicholas's surge resulted in flooding along the coast, particularly around Matagorda Bay.
