Pat Shingleton: "Coastal Lows..."
We're accustomed to low pressure systems originating on the Texas coast and eventually advancing to the Louisiana coast. These lows include one of many ingredients to send us into a soggy weather pattern that we are currently experiencing. Guiding these lows is the jet stream, that river of air at 25,000 to 35,000 feet. With already saturated ground, and an additional punch of rain, we run the risk of getting three inch amounts that could create flooding. Thus, a Flash Flood Watch is in effect through Thursday, alerting residents on the Amite, Comite, Tickfaw and Tangipahoa River basins. Model runs suggest an end by late Thursday night, giving us a window for float decorating in preparation for Saturday's "Wearin' of the Green" parade.
