Post-Tropical Cyclone 01L (Arthur) – Last Advisory

ARTHUR DEGENERATES TO A LOW PRESSURE AREA ALONG THE UPPER TEXAS COAST…LIFE-THREATENING FLOODING EXPECTED TO CONTINUE ACROSS PORTIONS OF THE SOUTHEASTERN UNITED STATES

According to the NHC Advisory number 8 

The post-tropical cyclone is moving toward the northeast near 9 mph. A northeastward motion at a faster forward speed is expected tonight, followed by a turn toward the east-northeast Thursday through Friday. On the forecast track, the remnants of Arthur should move farther inland over southeastern Texas and western Louisiana tonight, then cross the southeastern United States Thursday through Friday. Maximum sustained winds are near 35 mph with higher gusts. While additional weakening is expected as the system moves inland, the remnants of Arthur will continue to produce widespread heavy rains across the southeastern United States during the next few days.

HAZARDS AFFECTING LAND

RAINFALL: Tropical Storm Arthur is expected to produce rainfall totals of 5 to 10 inches, with isolated higher totals near 20 inches, through early Friday from the Mid and Upper Texas coast east-northeast into southern and central portions of Louisiana, Mississippi, and Alabama, along with western portions of Georgia and the Florida Panhandle. This could generate dangerous to life-threatening flash flooding.

WIND: Tropical storm conditions are expected within the warning area during the next few hours.

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

The deepest water will occur along the immediate coast near and to the east of the landfall location, 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.

SURF: Swells generated by Arthur are likely to cause life-threatening surf and rip current conditions along the northwestern Gulf Coast for the next day or two.

STORM SURGE: Water levels remain elevated along the Upper Texas coast but will continue to subside overnight.

TORNADO: A few tornadoes are possible late tonight across southeast Louisiana and southern Mississippi, and tomorrow into parts of Alabama, Georgia, and the Florida Panhandle.
