Hurricane Ida path, Louisiana landfall and information protection

Hurricane Ida lashed the state of Louisiana as a Class four storm for about six hours after it made landfall.

Ida was downgraded to a Class three storm in a 7 p.m. ET replace from the Nationwide Hurricane Heart. It made landfall as a Class four storm round 1 p.m. ET.

For reference, Hurricane Laura, which hit Louisiana final yr, went from a 150 mph Class four storm to 120 mph Class three storm in three hours after landfall. Hurricane Michael in 2018 went from 155 mph to 125 in three hours publish landfall. 

So Hurricane Ida maintained Class four energy after landfall for twice so long as these two storms.

So what is the distinction between classes anyway? The Nationwide Hurricane Heart uses the the Saffir-Simpson Hurricane Wind Scale to price hurricanes. Based on the dimensions, Class four hurricanes have sustained winds between 130 and 156 mph, and they’ll produce “catastrophic harm.”

“Nicely-built framed properties can maintain extreme harm with lack of a lot of the roof construction and/or some exterior partitions. Most bushes might be snapped or uprooted and energy poles downed. Fallen bushes and energy poles will isolate residential areas. Energy outages will final weeks to probably months. Many of the space might be uninhabitable for weeks or months,” the middle says of Class four storms.

In the meantime, Class three storms — which produce “devastating harm” — have sustained winds between 111 and 129 mph.

“Nicely-built framed properties could incur main harm or removing of roof decking and gable ends. Many bushes might be snapped or uprooted, blocking quite a few roads. Electrical energy and water might be unavailable for a number of days to weeks after the storm passes,” the middle says.
