... Flood Watch remains in effect through Tuesday afternoon...
The Flood Watch continues for
* portions of southeast Louisiana and southern Mississippi... including the following areas... in southeast Louisiana... lower Jefferson... lower Lafourche... lower Plaquemines... lower St. Bernard... lower Terrebonne... Orleans... St. Charles... St. John The Baptist... St. Tammany... Tangipahoa... upper Jefferson... upper Lafourche... upper Plaquemines... upper St. Bernard... upper Terrebonne and Washington. In southern Mississippi... Hancock... Harrison... Jackson... Pearl River... Pike and Walthall.
* Through Tuesday afternoon
* deep tropical moisture will move into the region from late tonight into Tuesday resulting in periods of heavy rainfall. Moderate durations of heavier rain may produce rainfall rates in excess of 2 inches per hour. Accumulations of 3 to 5 inches will be possible with locally higher amounts possible.
* Impacts include a likelihood of nuisance street flooding and ponding of water in poorly drained areas. There is a potential for flooding during periods of higher rain intensities that may threaten inundation of property and vehicles. In addition... communities near tidal influenced waterways may experience slow drainage due to higher than normal tides.
Precautionary/preparedness actions...
A Flood Watch means there is a potential for flooding based on current forecasts.
You should monitor later forecasts and be alert for possible flood warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.
Preparations should be made as soon as possible... before conditions deteriorate. Keep informed while listening for possible warnings. Secure loose outdoor objects which can be blown around. Strongly consider evacuating if you live in a Mobile home... and do so if ordered by local officials.
... Winds... as Hurricane Ida approaches... sustained tropical storm force winds are expected to begin late Monday afternoon and continue into Tuesday morning. Minor damage may occur to older Mobile homes. Residents should move loose items indoors... such as garbage cans and outdoor furniture... as they will be blown around. Newly planted or Young trees and shrubs may be uprooted if not secured properly. Isolated power outages will be possible.
... Storm surge and storm tide... tides are currently running around 2 feet above normal due to persistent east winds. Tides are expected to rise to 3 feet above normal by Monday afternoon. These high tide levels may lead to some Road closures by Monday afternoon. Minor storm surge flooding of 3 to 4 feet can be expected outside of hurricane protection levees and in areas around lakes Pontchartrain and Maurepas from Monday through Tuesday morning as Hurricane Ida moves through the coastal waters of Louisiana and Mississippi. Some non elevated homes in these areas may experience flooding. Minor to moderate tidal flooding of property and perhaps some flooding of low lying roads may occur during high tide.
... Inland flooding... a Flood Watch is in effect for the entire area. See latest forecast for latest information. Listen for possible flood warnings for your location... and be ready to act if flooding rains occur.
