re: General Tornado Thread

Reporting live from Memphis, TN. It is raining really hard. Occasional lightning and Thunder.

Flash floods warnings have been issued.

DirecTV still working like a champ though.

I was about to ask the same.

Is Shreveport looking free from any threat? Hour by hour is showing clear skies throughout the afternoon into the night.

Windy as hell though, had a hard time keeping it straight to Ruston and back..

30% chance of a tornado forming within 25 miles of any point in the shaded area. the black hatch marks show a 10% chance of an ef2+ tornado forming within 25 miles of any point in the area.

Great, we are just inside the high risk area

Whoa, PDS Tornado Watch released now for central Arkansas.

For those who don't know what a PDS watch is:

PDS watches are quite uncommon; less than 3% of watches issued by the SPC from 1996 to 2005 were PDS watches, or an average of 24 each year.[2] When a PDS watch is issued, there are often more PDS watches issued for the same weather system, even on the same day during major outbreaks, so the number of days per year that a PDS watch is issued is significantly lower.

PDS tornado watches are issued when there is a higher than normal risk of multiple strong to violent tornadoes – especially those that are predicted to be long-track in nature, with path lengths of more than 20 miles – in the watch area (usually amounting to damage consistent with EF4 or EF5 tornadoes), in addition to including significant wind and hail damage. While there are no set criteria for a PDS watch to be issued, they are usually issued when the potential exists for a major tornado outbreak. These types of tornado watches represent about 90% of PDS watches issued by the Storm Prediction Center.[2]

I thought PDS stood for "Pretty Damn Serious".

basically the same thing.. PDS watches are rare though, I'd hate to be in Central AR.. well I'd actually like to be there, but i'd hate to live there.

Going to share this on SEC rant
