Evolution of a Gulf hurricane, from Tropical Storm to Category 4 in five days...

Rob Perillo Chief Meteorologist KATC
5 day evolution of Hurricane Michael. A 40 mph tropical storm to high end Category 4 storm with 155 mph winds in 72 hrs. Another tropical system that reminds us how quickly storms can intensify with devastating results. Incredible how the storm strengthened & eye became most perfect right at landfall. Another storm for the record books...the name will be retired this offseason, but the rebuilding will last for years.

How accurate were the flood maps at Mexico Beach?

Analysis by Blair Tormey and Katie Peek shows that roughly 80% of structures are gone or severely damaged by storm surge, in an area mapped as minimal flood hazard (FEMA's X Zone).

As such, none of these structures would have been required to carry flood insurance (only zones V and A).

The X Zone is defined as an area of minimal flood hazard, outside the 0.2% annual-chance flood (or 500-year flood).

61% of structures in the expanded study area (Canal to the east end of town) are gone or sustained major damage. The west end was severely impacted, where entire houses were transported up to 500 feet by storm surge (see photo).

New video from WXChasing showing the devastation at ground level in Mexico Beach, FL. This is the exact area that we mapped and posted about on Friday. Notice the volumes of deposited sand and entire houses carried off their foundations and transported inland. This is the work of a powerful storm surge (not wind).

The video starts driving east on Hwy 98 looking landward, then returns back to the west, looking seaward.

Hurricane Michael produced a storm-surge debris line in Mexico beach, FL just as Hurricane Katrina did in Mississippi. Spectacular. It will be interesting to see why the homes that remained intact survived. ... See MoreSee Less

Satellite intensity estimates are rising this afternoon as the eye of Hurricane Michael cleans out. Dual channel outflow in place north and south of the storm. Here we go, folks. Michael will probably reach peak intensity in the next 12 hours, and make cat 3 in this evening. Category 4 not out of the question.

Written forecast out by 6:30p.
