System type: Tropical storm

System name: Arthur

The National Hurricane Center's 11 a.m. Wednesday advisory reported that the system strengthened enough to get a name: Tropical Storm Arthur. It found new strength and had evolved from a potential tropical cyclone into a tropical storm with sustained winds of 40 mph. The system's new name was first made public in the 11 a.m. advisory. Tropical Storm Arthur is 40 miles east-northeast of Port Oconnor, Texas and 190 miles west-southwest of Lake Charles, Louisiana. It is moving northeast at 9 mph, with maximum sustained winds of 40 mph.

"... the low pressure area should move northeastward along the Texas coast today and then move inland over southwestern Louisiana by tonight," according to analysts. They also said "Little change in strength is expected before the center moves over land."

Forecasters issued a tropical storm warning for portions of the Louisiana coast.

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 today. Tropical storm force winds, especially in gusts, are possible within the watch area today.

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...

Port Bolivar, TX to Morgan City, LA...2-4 ft

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.

For a complete depiction of areas at risk of storm surge inundation, please see the National Weather Service Peak Storm Surge Graphic, available at hurricanes.gov/graphics_at1.shtml?peakSurge.

Surf. Swells generated by Arthur are likely to cause life-threatening surf and rip current conditions along the northwestern Gulf Coast for the next couple of days.

Tornado A couple of tornadoes are possible through Thursday from the Upper Texas Coast into southern Louisiana, Mississippi, Alabama, and the western Florida Panhandle.
