It will then pass the long way across the Gulf of Mexico, gaining strength every day. Ida will probably be a Category 3 hurricane by the time it has crossed the gulf. There is a chance Ida could rise in strength to Category 4. It is too early to say for sure, but every single model but one that I’ve seen puts landfall somewhere in Louisiana. The one outlyer model has landfall in Mississippi near the Louisiana border.

Gulf-denizens, start getting ready now. Ida is moving fast. The landfall of the eye, which is NOT when it hits the coast, will be late Sunday or very early Monday.

Update: Latest info from NWS indicates that the storm will strengthn to Category 4 prior to landfall. That would be at about 6AM on the 30th.

  1. Life-threatening storm surge and hurricane conditions are
    expected to continue through tonight in portions of western Cuba,
    including the Isle of Youth, where a Hurricane Warning is in effect.
    Life-threatening heavy rains, flash flooding and mudslides are
    expected across Jamaica, the Cayman Islands, and western Cuba,
    including the Isle of Youth.

  2. There is a danger of life-threatening storm surge inundation
    Sunday along the coasts of Louisiana and Mississippi within the
    Storm Surge Warning area. Extremely life-threatening inundation of
    10 to 15 feet above ground level is possible within the area from
    Morgan City, Louisiana, to the Mouth of the Mississippi River.
    Interests throughout the warning area should follow any advice given
    by local officials.

  3. Ida is expected to be an extremely dangerous major hurricane when
    it reaches the coast of Louisiana. Hurricane-force winds are
    expected Sunday in portions of the Hurricane Warning area along the
    Louisiana coast, including metropolitan New Orleans, with
    potentially catastrophic wind damage possible where the core of Ida
    moves onshore. Actions to protect life and property should be rushed
    to completion in the warning area.

  4. Ida is likely to produce heavy rainfall later Sunday into Monday
    across the central Gulf Coast from southeast Louisiana to coastal
    Mississippi and Alabama, resulting in considerable flash, urban,
    small stream, and riverine flooding impacts. As Ida moves inland,
    flooding impacts are possible across portions of the Lower
    Mississippi and Tennessee Valleys.
