The Meteorology Thread: Hector Lives

Recommended Posts

Tropics are putting on a big show in the Pacific. Hector is near Cat 5 and will brush Hawaii (shouldn't be too bad);

(satellite resolution is bad because GOES-16 is at a pretty high angle, it's meant for storms further east)

 

 

Meanwhile, John is rapidly intensifying and murdering Ileana;

Also, per NHC, stations onshore are starting to report sustained hurricane force winds.

I'm currently in the middle of North Carolina. Most of the immediate concern here is the flooding. Aside from simply swamping things with water, the other big issue is that our sandy soil doesn't absorb water well, meaning that things like trees and telephone poles have tendency to become loose and then fall.

The landfall intensity was estimated at 135 kt (155 mph), which makes Michael the strongest hurricane to make landfall in the continental U.S. since Andrew (1992). The minimum pressure at landfall was estimated at 919 mb, which is the third lowest landfall pressure in the United States. A University of Florida/Weatherflow observing site measured a minimum pressure of 920.2 mb.

Hurricane Michael also resulted in the appearance of the rarest NWS advisory, the Extreme Wind Warning.

The Extreme Wind Warning was created after the 2005 season, when NWS offices in Mississippi and Louisiana issued tornado warnings for counties that were going to be affected by Katrina's winds, but weren't actually getting hit by tornadoes.
