Ida now dangerous Cat 4 hurricane: Timeline and expected landfall

Hurricane Ida strengthened into a Category 2 storm on Saturday. The storm is forecasted to become a dangerous Category 4 storm before it potentially makes landfall in Louisiana on Sunday.

HURRICANE IDA

FOX 35 Storm Team Meteorologist Allison Gargaro said rapid strengthening of the storm is expected over the next 12 hours.

She said, however, it could make landfall in Louisiana on Sunday as a Category 3 storm, which is still extremely dangerous.

Satellite imagery indicates that Ida's maximum sustained winds remained at 105 mph in the National Hurricane Center's 11 p.m. update. Ida is moving northwest at 16 mph.

The NHC said life-threatening storm surge, potentially catastrophic wind damage and flooding are expected to impact the northern Gulf Coast beginning Sunday morning.

Weakening is expected after Ida makes landfall.

This month marks the 16th anniversary of Katrina's landfall as a Category 3 storm with 125 mph winds.

Katrina is blamed for an estimated 1,800 deaths from the central Louisiana coast to around the Mississippi-Alabama state line. 

TROPICAL DEPRESSION 10

Tropical Depression 10 formed in the Atlantic and could become a tropical storm on Sunday.

The NHC said the storm is moving north at 10 mph with maximum sustained winds of 35 mph.
