The eyewall of Ida is now starting to move onshore just to the south-southwest of Grand Isle and just south of Leeville, very close to Port Fourchon. Here is the latest data from the NHC:

An elevated NOAA C-MAN station at Southwest Pass, Louisiana, recently reported a sustained wind of 89 mph (143 km/h) and a wind gust of 104 mph (167 km/h).

Within the past hour, sustained winds of 44 mph (70 km/h) and a gust to 60 mph (96 km/h) was reported at Lakefront Airport in New Orleans.

A NOAA National Ocean Service tide gauge in Shell Beach, Louisiana, recently reported a water level of 6.0 feet above mean higher high water, which is an approximation of inundation in that area.

A NOAA National Ocean Service tide gauge at Bay Waveland Yacht Club, Mississippi, recently reported a water level of 5.4 feet above mean higher high water, which is an approximation of inundation in that area.
