Louisiana-based Robert Rix Jr., a forecaster with the National Oceanographic and Atmospheric Administration, issued an advisory Friday afternoon that indicated Sunday's potential of a "...strong to severe thunderstorm threat...to develop and move along the immediate coast." Rix added that the the system could trigger storms that could produce "...localized damaging winds, waterspouts in the coastal waters and isolated tornadoes. The area of concern at this time should be limited to areas near the coast, but could extend farther inland to the tidal lakes if the low should move inland...the threat will end as the low moves east of the Mississippi coast and weaken."
