Strongest NWS Hurricane Ever Recorded Springs Up Over Night [Greg Laden's Blog]

(Before It's News)

Holy cow, man. Patricia, an Eastern Pacific Hurricane, became what is probably the strongest hurricane ever recorded by the National Weather Service in the NWS Hurricane Center’s area of responsibility (AOR), which consists of the Atlantic and the Eastern Pacific.

The storm is heading straight for Mexico. This is serious.

There are various ways to measure hurricanes. Maximum wind speed, central pressure (lower is badder), overall size (of hurricane force wind field), and overall total strength (using one of a couple of different metrics). Although weather forecasters and normal people tend to focus on wind speed hurricane experts are more impressed with central pressure. These things are all related, of course. But Patricia is the strongest hurricane with respect to its central pressure, and winds.

From the NWS:

Data from three center fixes by the Hurricane Hunters indicate that the intensity, based on a blend of 700 mb-flight level and SFMR-observed surface winds, is near 175 kt. This makes Patricia the strongest hurricane on record in the National Hurricane Center’s area of responsibility (AOR) which includes the Atlantic and the eastern North Pacific basins. The minimum central pressure estimated from the aircraft data, 880 mb, is the lowest ever for our AOR. It seems incredible that even more strengthening could occur before landfall later today, but recent microwave imagery shows hints of a concentric eyewall developing. If the trend toward an eyewall replacement continues, it would cause the intensity to at least level off later today. The official forecast shows only a little more strengthening before landfall. Given the very mountainous terrain that Patricia should encounter after landfall, the cyclone should weaken even faster over land than predicted by the normal inland decay rate.

The storm will hit Mexico as a strong category 5, the kind of category 5 that makers you wonder why there is not a cateory 6, TODAY (Friday). Incredibly, the storm is expected to get STRONGER before that happens. Winds will reach 200 miles per hour before landfall.

Huge coastal waves, a huge storm surge, intensive inland flooding are expected. This is a catastrophe unfolding.
