Extensive street flooding and flooding of creeks and rivers are possible. * ADDITIONAL DETAILS... - There is an increased risk to lives and property due to flash flooding. Flash Flooding is likely and considerable flash flooding is possible. Coastal areas will have the greatest potential for flooding overnight into Wednesday as Potential Tropical Cyclone One skirts along the Upper Texas Coast. Rainfall rates could exceed 4 inches per hour in the heaviest downpours. Additional widespread rainfall amounts of 2 to 4 inches with isolated higher totals possible especially along the coast. Grounds are fairly saturated across portions of Southeast Texas which would allow for a quicker transition of the rainfall to runoff. This increases the potential for street flooding, especially in the areas that have received 4+ inches of rain over the past few days. - Http://www.weather.gov/safety/flood
