Key messages for Nicholas can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT4, WMO header WTNT44 KNHC and on the web at hurricanes.gov/graphics_at4.shtml?key_messages

RAINFALL: Nicholas is expected to produce additional rainfall of 5 to 10 inches from the upper Texas coastal area into central to southern Louisiana, far southern Mississippi and far southern Alabama, with isolated storm totals of 20 inches across central to southern Louisiana. Life threatening flash flooding impacts, especially in urbanized metropolitan areas, are possible across these regions. Widespread minor to isolated major river flooding is expected across portions of the upper Texas Gulf Coast and southern Louisiana and Mississippi. For the latest rainfall reports and wind gusts associated with Hurricane Nicholas see the companion storm summary at WBCSCCNS4 with the WMO header ACUS44KWBC or at the following link https://www.wpc.ncep.noaa.gov/discussions/nfdscc4.html

STORM SURGE: The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... Sargent, TX to High Island, TX including Galveston Bay...3 5 ft High Island, TX to Rutherford Beach, LA...2 4 ft Port Aransas, TX to Sargent, TX...1 3 ft Aransas Bay, San Antonio Bay, and Matagorda Bay...1 3 ft Rutherford Beach, LA to Intracoastal City, LA...1 3 ft Sabine Lake and Calcasieu Lake...1 3 ft The deepest water will occur along the immediate coast in areas of onshore winds, where the surge will be accompanied by large and dangerous waves. Surge related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office.

WIND: Tropical storm conditions are expected to continue within the warning area across Texas coasts through this morning and start along the Louisiana coast by afternoon.

TORNADOES: A tornado or two will be possible today and tonight along the upper Texas Coast and southern Louisiana.

SURF: Swells generated by Nicholas will continue affecting portions of the northwest Gulf coast today. These swells are likely to cause life threatening surf and rip current conditions. Please consult products from your local weather office.
