The system is moving toward the northwest near 5 mph (7 km/h). A slow northwestward to northward motion is expected over the next day or so, followed by a faster motion to the northeast beginning late Tuesday. On the forecast track, the disturbance is expected to move just offshore of the northern Gulf Coast of Mexico through Tuesday, and approach the Upper Texas and Louisiana coastline on Wednesday. Air Force reconnaissance data indicate that maximum sustained winds are near 50 mph (85 km/h) with higher gusts.

Tropical-storm-force winds extend outward up to 185 miles (295 km), primarily west of the center. The estimated minimum central pressure is 1003 mb (29.62 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are possible within the watch area along the northern coast of Mexico beginning Tuesday. RAINFALL: Potential Tropical Cyclone Six is expected to bring storm total rainfall of 4 to 8 inches, with local amounts to 12 inches, from the coast of far northeast Mexico northward along portions of the Texas Coast and into Louisiana through Thursday. This rainfall would lead to the risk of flash and urban flooding. For a complete depiction of forecast rainfall associated with Potential Tropical Cyclone Six, 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. STORM SURGE: Minor coastal flooding is possible along the Mexico coast within areas of onshore flow. SURF: Swells generated by this system are affecting portions of the Gulf coast of Mexico and are expected to spread northwestward across the northwestern Gulf of Mexico coastline through midweek. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
