Atlantic Ocean:Tropical Storm 07L (Gonzalo)
According to the NHC, Gonzalo is moving toward the west near 17 mph (28 km/h). A general westward to west-northwestward motion is expected for the next couple of days.
On the forecast track, Gonzalo will move across the southern Windward Islands this afternoon or evening and over the eastern Caribbean Sea on Sunday. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts.
Little change in strength is expected before Gonzalo reaches the southern Windward Islands. Weakening is expected after Gonzalo moves over the eastern Caribbean Sea, and the system is forecast to dissipate by Sunday night or Monday.
Data from the Hurricane Hunter plane indicate that the tropical-storm-force winds extend outward up to 25 miles (35 km) from the center.
>>> A tropical wave is producing an area of disorganized showers and thunderstorms a few hundred miles south of Cabo Verde Islands. This wave is expected to move westward during the next several days, and it could become a tropical depression early next week when it reaches the western tropical Atlantic.

Gulf of Mexico: Tropical Storm 08L (Hanna)
According to the NHC, Hanna is moving toward the west near 8 mph (13 km/h) and this motion should continue through Saturday morning. A gradual turn toward the west-southwest is expected Saturday night and that motion should continue through Sunday.
On the forecast track, the center of Hanna should make landfall along the Texas coast within the hurricane warning area Saturday afternoon or early evening. Maximum sustained winds are near 65 mph (100 km/h) with higher gusts.
Additional strengthening is forecast, and Hanna is expected to become a hurricane before the cyclone makes landfall on Saturday. Rapid weakening is expected after Hanna moves inland.
Tropical-storm-force winds extend outward up to 80 miles (130 km) from the center.
HAZARDS AFFECTING LAND
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…
Baffin Bay to Sargent TX…including Corpus Christi Bay, Copano Bay,
Aransas Bay, San Antonio Bay, and Matagorda Bay…2 to 4 ft Mouth of the Rio Grande to Baffin Bay TX…1 to 3 ft North of Sargent to High Island TX…including Galveston Bay…1 to 2 ft
The deepest water will occur along the immediate coast near and to the right of the landfall location. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances.
WIND: Hurricane conditions are expected in the warning area Saturday afternoon. Tropical storm conditions are expected to begin in the warning area tonight or Saturday morning.
RAINFALL: Hanna is expected to produce 5 to 10 inches of rain with isolated maximum totals of 15 inches through Sunday night in south Texas and into the Mexican states of Coahuila, Nuevo Leon, and northern Tamaulipas. This rain may result in life-threatening flash flooding, rapid rises on small streams, and isolated minor to moderate river flooding in south Texas.
3 to 5 inches of rain is expected along the upper Texas and Louisiana coasts.
SURF: Swells generated by Hanna are expected to increase and affect much of the Texas and Louisiana coasts during the next few days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
TORNADOES: A brief tornado or two will be possible, mainly overnight, across portions of the upper Texas and Louisiana Coasts.
