Damage surveys continue in the Plains in the wake of Saturday's major tornado outbreak. NOAA's Storm Prediction Center logged 110 preliminary tornado reports, with an additional 10 reports from Sunday. At least one tornado was a violent EF-4, which hit mostly unpopulated areas in Ellsworth County, Kansas. The only fatalities from the outbreak occurred in Woodward, Oklahoma, where an EF-3 tornado hit at night after lightning knocked out the town's tornado sirens. Six people were killed, three of them children. A preliminary rating of EF-3 has also been given to a tornado that hit the south and southeast portions of Wichita, Kansas near 10:30 pm CDT Saturday night. The tornado did significant damage to McConnell AFB and to a nearby trailer park. All of the residents of the trailer park were in the trail park's tornado shelter, which undoubtedly saved many lives. Two residents required hospitalization. Damage from the Wichita tornado has been estimated at $283 million.

New dire language in tornado warnings
National Weather Service offices in several states in the Plains are experimenting this year with new wording in public advisories when a particularly dangerous tornado has touched down. If spotters confirm that a large and damaging tornado is on the ground, the NWS has the option of including some rather dire wording to get the public to take action. About 3/4 of all tornado warnings are false alarms. This primarily occurs because the NWS will issue a warning for a rotating thunderstorm spotted on radar, and these thunderstorms don't always have funnel clouds that reach to the ground. But when spotters actually verify that a tornado is on the ground, and that tornado has a long history of causing damage, issuance of one the new direly-worded advisories may help give the public the message that this tornado is not going to be a false alarm and they better take it seriously. Such an advisory was issued for Saturday's Wichita, Kansas tornado, which turned out to be an EF-3 that caused major but not catastrophic damage. The dire wording of the advisory predicted the type of damage associated with a violent EF-4 or EF-5 tornado, "with complete devastation likely." The damage from this tornado fell short of that mark, but I believe it was a reasonable usage of the new type of advisory:

Spring brings Radioactive?? fallout
Source: Fairbanks Daily News-Miner
Date: Apr 15, 2012

Editorial Editors note: This spring, Alaskans read news of how Japan%u2019s Fukushima nuclear reactors were still leaking radioactivity a year after being destroyed by a tsunami. Fifty years ago, Alaskans were worrying about a different source of radioactivity, as explained in this Daily News-Miner editorial from April 12, 1962.

Spring is upon us, but we will have to face more than the return of the birds and the happy loss of the snow, for in this nuclear age the spring fallout from last year%u2019s Russian nuclear tests is beginning to show up. [...]

Fallout, the radioactive debris of nuclear explosions, settles on all parts of the earth%u2019s surface [...]

This we can apparently do little about, and for that matter, little is known about the effects of fallout radiation on the human body. [...]

As we said before, the heaviest concentrations of fallout are found between 30 and 50 degrees North latitude, a zone that includes virtually all of the continental United States.

But before we become unduly alarmed it should be pointed out that the Public Health Service feels there will be no need for special protective measures to reduce human intake of radioactive strontium 90, which may cause bone cancer or leukemia, and cesium 137, which is believed to cause malevolent genetic mutations. [...]

Well the tornado Dr Masters mentioned did not meet the warning, so already thats one "cry wolf", it won't take long before they don't work again. Basically if your blasie or stupid you could be killed by a tornado, and thats your problem, imho.
Also you could just be plain unlucky and get killed.


What about the warning for Wichita was not correct or was a cry wolf?

Imagine..being stuck in traffic...and THIS happens..omg...............................Event
Intense thunderstorms raked the highly populated McAllen/Edinburg/Mission area of Hidalgo County during the mid evening of March 29th. The storms dumped hail up the size of baseballs for more than half an hour, drove that hail with 70 to 75 mph winds, added 4 to 6 inches of torrential rains, and produced frequent cloud to ground lightning. Initial storms developed across the King Ranch during the mid afternoon of March 29th, and spread west into northern Hidalgo and Starr County by early evening. The storms, fed by warm, humid air near the surface, colder air aloft, and boundaries (providing lift) from earlier storms which moved across the Coastal Bend, appeared to have intensified further as they approached the highly populated Edinburg/McAllen/Mission area. Why they intensified was a mystery, but one possibility was the interaction with an upper level disturbance moving across northeast Mexico. This disturbance spawned dangerous storms in Nuevo Léon and Tamaulipas, and boundaries from these cells may have been the ultimate trigger to a night hundreds of thousands will not forget.

Quoting RTSplayer:
Radar estimate at Corpus is up to 16.5 inches of total accumulation.

Should have seen last night near Zapata county Texas.
2 consecutive hours of 5.8 to 5.9 inches per hour rainfall rates estimated by radar.

I think it was officially raining over 3 inches per hour, according to the flash flood warning's description.


Using the NWS multi-sensor best estimate product that is produced by the river forecast centers, there is a small area a 12-14" estimate for the last 12hrs (ending at 15z). Most areas between Corpus Cristi and Bayside are now ranging from 6-12" of rainfall.
http://www.srh.noaa.gov/ridge2/RFC_Precip/

A bit over 10" of that rainfall occurred over the last 6hrs. The 1%-chance event (a.k.a. 100yr ARI) is about 8-9".

Similar in size and magnitude to the Lafayette/Carencro, LA, flash flood event earlier this year.

But at the same time, they should be used sparingly and only when appropriate. If not, we will begin to recreate the same problem that necessitated the harsher wording to begin with.

So you think we will get 6"-10" of rain in the greater Houston area? These storms seem to be training along the cost (south of 59 corridor) and a few hours north of 59 but almost everything is south of I-10.

If we get 6"+ out of this, I will be ecstatic but I don't know if that will actually happen. I can only hope it does though :D

Based on the NWS discussion, the rain amount depends on if the front backs up as a warm front, stays stalled, or ends up pushing off the coast.

Backs up as a warm front - widespread 1" amounts possible, with isolated totals in the 3-5" range.
stays stalled - areas north of the boundary will be lucky to get 0.5", areas south of the boundary are looking at 1-3".
pushes off - get your sprinklers, you're going to need them after getting <1".

Some areas of coastal TX are approaching 14". Amazing as this is on the level of TS Alison rains. RitaEvac stay safe man as these rains are heading your way. You could easly get 6" to 10" from this event.

Some areas of coastal TX are approaching 14". Amazing as this is on the level of TS Alison rains. RitaEvac stay safe man as these rains are heading your way. You could easly get 6" to 10" from this event.

Long time lurker first time poster. I actually live in Portland, TX. It has been raining cats and dogs since 5 am this morning. What a way to wake up, step outside and have the tornado alarms go off. Sheltered for a while, came back out, sheltered again when the sky went green. I can't go anywhere, streets are like rivers. I've been through a hurricane before and never saw it come close to like it was raining earlier. I am not going anywhere for a while. My rain gage goes up to 6 inches and it has been overflowwing for a couple of hours now. I hope this "training" stops soon...


Are the cats and dogs fighting or they getting alone fine, lol.

Stay safe mate. I'm watching it from afar, the best place to be in wild weather.

Even in the best of circumstances, sometimes the Weather can overwhelm the best of Mans inventiveness.

We pray for the lost and their families...and for all who suffered loss from this latest system.


Have a weather alert radio at the ready for Severe Storm Season is here.

The wording is impressive. What I remember is the "THE EXTREME DEVASTATION WILL RENDER THE AREA UNRECOGNIZABLE TO SURVIVORS". Made me want to hide even though I am nearly 2,000km away from the tornadoes.

Can only imagine reading that in a path of a tornado.


I read those words and a shiver went right down my spine and I got instant goosebumps, then I turned on my radio scanner app on my phone and heard those same words. I was um, pooping my pants and i'm 14,000km's away.

I guess they really need to get the message into peoples heads how dangerous the tornado is. Just wish the 6 people that died in Woodward, OK had heard those words and get to a safe place.

Lol you and I both. I don't even know what would be going through my mind in the path of a tornado on the ground and my weather radio telling me I am going to die and my house will disintegrate.


But the NWS needs to use words like that to get it through peoples heads that it is a serious situation and they need to take cover. So many people just blow that kind of stuff off and then it is to late.

Now somebody last night posted where the front stalls out along the TX/LA coast and brings rain for the next 48hrs as a low pressure forms in the western gulf along the front and moves NE riding the coast. After seeing shower activity wayyyy back near San Antonio, makes me wonder if that is going to happen. Clouds have thicken way back in SC TX


That is a good sign for us. Maybe some widespread inch per hour precip will develop

Actually the video i watch, the tornadoes were right beside each other... maybe 1/2-1 mile apart. I'll post it so you can see.


I've already seen it.


He actually manages to get them both in one shot a few times.


You can also get multi-vortex and horizontal vortex tornadoes orbiting the main one withing a few dozen to a few hundred yards.

Personally, I think all "wedge" tornadoes are probably multi-vortex, you just can't necessarily see it from the outside.
