* WHAT...Flooding caused by excessive rainfall continues to be possible. * WHERE...Portions of south central and southeast Texas, including the following areas, in south central Texas, Coastal Jackson and Inland Jackson. In southeast Texas, Brazoria Islands, Coastal Brazoria, Coastal Galveston, Coastal Matagorda, Fort Bend, Galveston Island, Inland Brazoria, Inland Galveston, Inland Matagorda, Matagorda Islands and Wharton. * WHEN...Through Monday morning. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Flooding may occur in poor drainage and urban areas. * ADDITIONAL DETAILS... - Areas along the coast, especially Matagorda and Brazoria Counties, received 6-8" of rainfall over the past two days. These areas in particular are vulnerable to additional rounds of rainfall over the next 24-48 hours, which brings the potential for flash flooding. The next round of rain is expected late this evening or Friday morning. Rainfall rates are expected to peak in the 3-4+" per hour range in the heaviest downpours. Additional rainfall totals through Monday are anticipated to be in the 4-6" range with isolated higher totals. The Flood Watch will likely be expanded going into the weekend. - http://www.weather.gov/safety/flood

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
