Dangerous Flooding Situation 6/9/2010

[ticka1]

Due excessive rainfall over Central Texas - dangerous flooding situation is unfolding near San marcos, New Braunfels and all the rivers are flooding.

This rain event could slowly move south and east and affect us here in SE texas. Keep an eye on the weather and radars.

I will post Jeff's emails here in a few mins.

Flash Flood Event unfolding over the northwestern parts of SE TX.

Radar indicates 3-4 inches of rain has fallen in the last 2 hours from College Station to near Giddings with totals of 5-6 inches over central Lee County.

Thunderstorms producing excessive rainfall continue to develop in a nearly stationary band from W of Huntsville to N of Columbus. An additional 2-4 inches of rainfall on top of what has fallen can be expected in the next 1-2 hours.

Mid level tropical low situation near Austin continues to favor intense development along a line from Huntsville to near San Marcos. Activity near San Marcos is starting to move ESE and increase in forward speed and this will likely begin to impact a greater portion of SE TX in the next 1-2 hours. Flooding and flash flooding will be the main threat.


From Jeff. I emailed him and asked him about Houston/downtown area. The next post is his reply.

More and likely…it will probably push southward slowly as a cold pool develops into the moist Gulf feed. Also as we heat additional cells may begin to develop out ahead of the main band.

Will this affect the Houston/downtown area or more for the counties north of Houston?

Tornado Watch - not all of SE texas - northern ones.

Tornado Watch issued for the northern half of SE TX until 300pm.

Tropical air mass being heating is becoming very unstable. Nearly stationary tropical low to the west is supporting favorable shear profiles for low topped supercells with brief tornadoes to develop. With Gulf inflow increasing, weak short lived tornadoes will be possible through mid afternoon.

Flash Flood threat is of much greater concern with Flash Flood warnings now in effect for Grimes, Brazos, and northern Washington counties. Appears a very slow moving MCS may be developing with potential to drop 4-8 inches of rainfall in a few hours. Additional massive cell over Comal County, TX is approaching our western counties with cloud top of 72,000 ft. Rainfall rates under this cell per satellite products may be on the order of 3-5 inches.

Just saw a post on FB from TWC that they are doing rooftop rescues in Seguin and New Braunfels in Comal and Guadalope counties. Will try to find links online and post them here. Dangerous situation with all those vacationers down there on the Rivers.

Isn't this the same area that was in Drought last year?What does that say for current weather and La Nina vs El Nino?

Just saw where they've found the body of a 20th victim in the Arkansas flash flooding. So sad http://www.msnbc.msn.com/id/37681729/ns/us_news-life/

Now they are experiencing flash flooding in the OK City area; downtown area is flooded and parts of 3 interstates are closed due to flooding.

Not to make light of this serious situation, but I'm starting to think about adding floaties to my truck emergency kit. But seriously if you don't have a Lifehammer or something similar it might be worth checking into. http://www.lifehammer.com/ Something to cut your seatbelt and break out your car window if need be.

[ticka1]

I thought of that after Allison TSD - but never followed thru - I thought about just having something to float on - I am not a very good swimmer. Gives you something to think about. Man OKLA is having the weather this year.

[Texas SpeedDiva]

I've got a seperate belt cutter and punch for the window but have been seriously considering getting one of the ResQ deals or LifeHammer. Since it's an all in one deal

Its been flooding in Central Wyoming (Lander/Riverton area) now for just over a week. This is an area that hasn't experienced a flood in many decades and is starting to bring hope that maybe the very long drought might be coming to a close.

LANDER -- For 30 years, Carolyn McIntyre has lived along the North Fork of the Popo Agie River, watching it rise and fall nearly every spring. But this week the river raged like never before, tearing away large trees and part of the riverbank behind her home.

The river eroded part of McIntyre's gravel driveway and, at one point on Monday, surrounded her 100-year-old house before subsiding and leaving behind broken branches, busted buck and rail fences and scattered debris. A small nature path was washed away or remained under water.

"The thing is that there were other tasks that we had to do for maintenance around the place this year, and now those will have to be put off because this will have to be fixed," McIntyre said Friday. "So that's it. There was nothing scary about it, but it was dissettling."

A rapid snowmelt combined with rain over the past week has sent rivers and creeks to record levels, washing out several bridges, closing roads and flooding or threatening about 140 homes along rivers in the towns of Lander and Hudson and Wind River Indian Reservation communities of Arapahoe, St. Stephens, Ethete and Fort Washakie. No deaths or major injuries have been reported, and no one has used Red Cross shelters.

Residents and emergency officials worked Friday to clean up the mess and build more sandbag dikes to protect their properties, mindful that flooding may return next week and push the rivers even higher.

The National Weather Service issued a winter storm warning for the eastern slopes of the Wind River Range, predicting up to 3 feet of snow in the highest reaches of the nearby mountains Friday night and today. Rain is expected in the river valleys.

More Flooding Possible In Central Wyoming
CHEYENNE, Wyo. (AP) ― More flooding is possible in central Wyoming following heavy snow that's fallen in the Wind River Range.

Fremont County incident commander Craig Haslam predicted that rising temperatures will begin melting the snow Tuesday, causing rivers to crest Wednesday and Thursday.

About 230 Wyoming National Guard troops are on hand to help officials and residents.

Floodwaters already have washed out bridges, closed roads and damaged homes in an area of about 32 square miles, most of it undeveloped or agricultural land.

Meanwhile, in south central Carbon County, a flood warning is in effect through Monday afternoon.


Flooding in Laramie as well:

Water from runoff, rainstorms and reservoirs will continue to make a mess in Laramie and around southeast Wyoming for at least a couple more days, National Weather Service Meteorologist Scott Carpenter said.

“We’re still looking at another half an inch of rainfall there in town and then in the late afternoon and evening this storm system’s going to pull off to the north and east, but we’ll still have some light showers around. But for the most part, accumulating rainfall will be down most of (this) week,” Carpenter said.


Flooding in Gillette:

The water in one river in flood-drenched west-central Wyoming has started dropping, but others continue to rise — and more moisture is on the way.

The National Weather Service has extended the flood warning for rain and melting snow in central Wyoming through noon Friday.

A significant rise in the middle fork of the Popo Agie River is expected later Thursday.

“This isn’t over yet,” said 2nd Lt. Christian Venhuizen of the Wyoming National Guard, which is making its largest in-state activation since 2000 in response to the flooding.


Flooding in Evanston:

Widespread flooding in Uinta County this week was caused by rapidly melting snow in the Uinta Mountains, creating havoc when the Bear River and other smaller tributaries swelled to record highs.

According to the National Weather Service website, the Bear River rose to a record 7.55 feet around 6 p.m. Tuesday, breaking the previous record of 7.35 feet set in 1984.
