Official Advisory Discussion

At 400 PM CDT (2100 UTC), the center of Tropical Storm Arthur was located near latitude 28.9 North, longitude 96.1 West. Arthur is moving toward the north-northeast near 7 mph (11 km/h), and this general motion should continue through tonight. On the forecast track, the center of Arthur should move farther inland over southeastern Texas tonight.

Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Weakening is expected as the low moves farther inland, and it could dissipate by tonight or early Thursday.

Tropical-storm-force winds extend outward up to 175 miles (280 km) from the center. NOAA buoy 42035 east of Galveston recently reported a sustained wind of 40 mph (65 km/h) and a gust of 52 mph (83 km/h).

The estimated minimum central pressure based on surface observations and aircraft data is 1001 mb (29.56 inches).

HAZARDS AFFECTING LAND

Key messages for Tropical Storm Arthur can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT1 and WMO header WTNT41 KNHC.

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.

For a complete depiction of forecast rainfall associated with Tropical Storm Arthur, please see the National Weather Service Storm Total Rainfall Graphic available at hurricanes.gov/graphics_at1.shtml?rainqpf and the Flash Flood Risk graphic at hurricanes.gov/graphics_at1.shtml?ero.

For a list of rainfall observations (and wind reports) associated with Tropical Storm Arthur, see the companion storm summary at WBCSCCNS1 with the WMO header ACUS44 KWBC or at the following link: www.wpc.ncep.noaa.gov/discussions/nfdscc1.html.

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…

Matagorda, TX to the Mouth of the Mississippi River, LA…1-3 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 information specific to your area, please see products issued by your local National Weather Service forecast office.

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 day or two. Please consult products from your local weather office.

A depiction of rip current risk for the United States can be found at: hurricanes.gov/graphics_at1.shtml?ripCurrents

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.
