* WHAT...Flooding caused by excessive rainfall is possible. * WHERE...A portion of south Texas, including the following areas, Aransas Islands, Bee, Coastal Aransas, Coastal Kleberg, Coastal Nueces, Coastal Refugio, Coastal San Patricio, Duval, Goliad, Inland Kleberg, Inland Nueces, Inland Refugio, Inland San Patricio, Jim Wells, Kleberg Islands, La Salle, Live Oak, McMullen, Nueces Islands and Webb. * WHEN...From Saturday afternoon through Monday morning. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. * ADDITIONAL DETAILS... - Widespread forecast rainfall amounts of 2-4 inches will be common across South Texas with high end amounts approaching 5 inches. Isolated amounts exceeding 5 inches remains a possibility, especially in the vicinity of training and slow moving storms. While soils will be able to absorb most of this moisture, the higher rainfall rates can quickly lead to localized, urban flooding and in locations with poor drainage. - 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.
