The National Weather Service has issued a coastal flood watch for southeastern Louisiana and southern Mississippi from Sunday morning through late Sunday night.
In June 2010, clouds loomed off the coast of Louisiana in the Gulf of Mexico.
Tides will be 2 to 4 feet above normal along coastal areas on Sunday afternoon and evening, with the main threat occurring during high tides.
The high tide levels may produce flooding in low-lying areas outside of hurricane protection levees in southeast Louisiana and low-lying areas along the Mississippi coast and Lake Pontchartrain.
The higher-than-normal tides will be produced by a strong low-pressure system moving along the Louisiana coastline on Sunday, which will be accompanied by strong winds. Prolonged easterly winds will create water levels several feet above normal until the winds relax Sunday night.
The mostly clear skies that are producing cool but balmy weather through Saturday should end in the early hours of Sunday, as light rains accompanied by high winds move into the area. By daytime Sunday, expect numerous showers and isolated thunderstorms, tapering off in the evening.
Expect high temperatures in the mid-50s and lows in the 40s through Sunday.
On Monday, mostly cloudy skies will be accompanied by highs only in the upper 40s.
