Now compare the forecast 500mb for later today, 00z February 02, 2016February 01, 2016Bloggfs_namer_024_500_vort_ht

with 12z February 05, 2008, the beginning of the Super Tuesday Outbreak that produced 87 tornadoes over two days killing 56.  The features the two maps have in common would include the event driving deep upper low vicinity Colorado/New Mexico Border, the kicker, just west of the Pacific Northwest, the next disturbance in the series and the polar vortex well north over Hudson’s bay.

So, heads up, weather folks are all bent out of shape about this one for a reason. If you do live in the yellow slight risk area, or orange enhanced region there is a real threat for damaging weather with the passage of this weather system.

Floods, snowstorms, and tornadoes oddly enough are all in my latest e-book El Niño:  The WILD side of the weather cycle…What we know, what we don’t, and WHY you should care!

I show how this years Pacific water temperatures compare to the 1983 and 1998 events and highlight the kind of weather episodes that these stronger El Niño’s tend to bring.

Hurricane moves away, but still a 1000 year flood

October 06, 2015 – Hurricane moves away, but still a 1000 year flood

Below are some of the highest rainfall amounts in Charleston County, South Carolina from the recent storm. These are four day amounts, Friday Oct. 2 thru Monday Oct. 5.  There is no landform that can absorb 26 inches of rain in less than 4 days. That is nearly 6 months of rain in 4 days.

The deluge continued into Saturday across mainly South Carolina.  Regional radar and water vapor imagery show the narrow channel of moisture  from the hurricane to South Carolina .

With both the Perfect Storm of October 1991, and the record Maine flood of October 1996, it was dying and decaying tropical systems that kicked in the excess moisture.

Water vapor image from midday Saturday showing a rare eye from Joaquin when the storm was near its strongest point.  The image was taken around the same time Air Force reconnaissance  survived a gust to 144 knots which is about 165 mph. The Hurricane Center briefly lifted top winds on the hurricane to 155 mph, just under Category 5 status.

MAX FL WIND 144 KT 148 / 14 NM 14:46:30Z

Maximum Flight Level Wind 144 Knots from 148 degrees or SSE, the observation occurred 14 nautical miles from the center of Joaquin at 14:46z or 10:36 AM EST  Saturday morning.

Again 144 knots is about 165 mph, all this from a VORTEX DATA MESSAGE sent by Air Force reconnaissance.  The entire message below includes a description of the ride into the storm and what they found when they got there,  Moderate turbulence inbound. Clear above in Center.

The rain Friday into Saturday was already creating a disaster, but the rain continued, and it continued across the same South Carolina counties thru Saturday, Saturday night and into Sunday.  Hurricane Joaquin traveled hundreds of miles and the moisture channel just pivoted with the storm never losing its connection to South Carolina.

The hurricane actually did just move away.  This is quite miraculous considering what some of the model forecasts were doing with a possible landfall.

So,  a unique event to be sure, we were fortunate the hurricane itself stayed far from the United States.  South Carolina did NOT get another Hugo.  But still got nailed with what is being called a “1000 year” event.  An event of this magnitude is expected once every 1000 years.

El Niño is still alive and well in early October, the most recent weekly region 3.4 anomalies are running dead even with 1997.  So, this El Niño thing is happening, we gotta be on guard.  The Joaquin situation evolved very quickly.  It really could have been any where along the coast.  So, who’s going to be next?  When is the next 1000 year flood?

More on these warm anomalies later this week.
