A Flood Advisory remains in effect through Friday morning for Harris, Galveston and Chambers Counties... as well as eastern Brazoria and east central Matagorda Counties. Rainfall of up to four inches per hour may cause flooding in Pasadena, League City, Baytown, and around the Galveston Causeway. Other locations that may experience flooding include Galveston Island's west end, Texas City, Friendswood, LaPorte, Deer Park, Lake Jackson, Alvin, Angleton, Dickinson, LaMarque, Santa Fe, Freeport, Seabrook, Clute, and Webster.
Forecasters are also watching a system they currently call 95-L, which has an increased chance of developing into a tropical system in the Gulf of Mexico.
"It'll probably start to approach the coastline in about three days, so toward the end of the week; and then would move across the coastline sometime maybe Friday night or Saturday."
National Weather Service Meteorologist Sean Luchs says there is a 60-percent chance the system will form into a tropical cyclone, storm, or even a hurricane.
Governor Greg Abbott has ordered the Texas State Operations Center (SOC) to elevate its readiness level effective at noon today. He issued a statement reading in part, 'in light of recent heavy rainfall across the state, we are on high alert as any additional rain could quickly create dangerous flash flooding conditions." The operations center encourages people to have an emergency kit ready, and discuss evacuation plans in case a hurricane threatens the region.
Meanwhile, the National Hurricane Center in Miami says Hurricane Isaac remains a category one storm as it steams to the west at 14-miles per hour. It's centered about 88-miles east of the Lesser Antilles with maximum sustained winds of 70-miles per hour. Forecasters expect it to move into the eastern Caribbean by Thursday, but it is uncertain whether it can survive the wind shear in the area and move into the Gulf in the future.
