Floods overwhelm North Dakota levees; floods kill 175 in China

Flood waters from North Dakota's Souris River are pouring over the levees protecting Minot, North Dakota today, and flood heights are expected to rise to the highest levels in recorded history tonight. The Lake Darling flood control reservoir located about 15 miles upstream from Minot is full to overflowing, and record releases of water are occurring to prevent the lake's dam from over-topping. By this weekend, the Army Corps of Engineers will open the dam's flood gates to a maximum flow rate of 20,000 cubic feet per second, which is roughly double the flow rate that the levees in Minot can handle. Water began flowing over the levees yesterday, forcing the mandatory evacuation of 12,000 residents. By Sunday, water levels on the Souris River are expected to peak at four feet above the previous all-time flood height, set in 1881. Torrential rainfall in Canada on Sunday and Monday, combined with very heavy rainfall and snow melt over North Dakota over the past month, are responsible for the record flood. The Souris River Basin near the Rafferty Dam in Saskatchewan received four to seven inches of rain Sunday into Monday. Flood heights along the Souris River near the Canadian border upstream from Minot are already two feet above the previous all-time highest mark, and that pulse of water is now arriving in Minot. The unprecedented flood is expected to keep much of Minot underwater for at least two weeks. Fortunately, no new heavy rains are expected over the next five days, though up to 1/2" of rain could fall over portions of the Souris River watershed.

Record rains in China kill 175, do $5 billion in damage
Torrential rains triggered severe flooding in eastern China this week, with the death toll for June floods now standing at 175, with 86 people missing. Ironically, the same region experienced severe drought at the beginning of June. The estimated $5 billion in damage from the floods would make 2011 the third most expensive year for floods in China in the past decade. This year is the second consecutive year floods have caused exceptional damage in China. Last year, Western China saw summer precipitation more than 200% above average, and torrential monsoon rains triggered catastrophic landslides that killed 2137 people and did $759 million in damage. Monsoon floods in China killed an additional 1911 people, affected 134 million, and did $18 billion in damage in 2010, according to the WHO Collaborating Centre for Research on the Epidemiology of Disasters (CRED). This was the 2nd most expensive flooding disaster in Chinese history, behind the $30 billion price tag of the 1998 floods that killed 3656 people. China had floods in 1915, 1931, and 1959 that killed 3 million, 3.7 million, and 2 million people, respectively, but no damage estimates are available for these floods. During the period 2000 - 2009, China averaged $3.7 billion in damage and 674 deaths per year due to floods and landslides, according to the WHO Collaborating Centre for Research on the Epidemiology of Disasters. This does not include the toll from typhoons. Speaking of typhoons, Tropical Storm Meari, currently located a few hundred miles east of the Philippines' Luzon Island, is expected to track north-northwestwards towards China today and Friday. By Saturday, Meari is expected to be a Category 1 typhoon, and will spread heavy rains over eastern China, worsening the flooding situation there--though the heaviest rains will likely remain offshore.



Figure 3. Rainfall amounts in excess of 18 inches (450 mm) fell in Eastern China southeast of Shanghai in a 1-week period, June 13 -19, 2011. A China Daily report from June 18 described the rains in parts of Zhejiang Province as unprecedented. High waters broke 100-meter (300-foot) holes in levees, inundating nearby villages. Some homes were buried in 3 meters (10 feet) of water. This image is based on data from the Multisatellite Precipitation Analysis produced at Goddard Space Flight Center, which estimates rainfall by combining measurements from many satellites and calibrating them using rainfall measurements from the Tropical Rainfall Measuring Mission (TRMM) satellite.

The Atlantic is quiet
The Atlantic is quiet, but several models, including the NOGAPS and GFS, are predicting that a tropical disturbance capable of becoming a tropical depression could form in the southern Gulf of Mexico in the Bay of Campeche Tuesday or Wednesday. There will be a strong ridge of high pressure over the Gulf next week, which would tend to keep any storm that might form far to the south, with impacts limited to Mexico and perhaps South Texas.

My parents were living in Dakota Dunes, SD- a few blocks from the flooding Missouri. They were evacuated a few weeks ago. My mother reported that the Dam in Yankton, SD- just up river- now has 33% more water flowing through it than the Niagara Falls.

I cannot confirm this information.

We are seeing the same pattern as last year...The ridge is in the right place at the right time forcing all the systems westward. Last year it was all Mexico and no systems could move north into the Gulf. Rain is needed from these systems.

I am not giving up hope yet, that blob in the GoM right off the Texas coast might either move inland into Texas or help pull the TW into Texas. Ok, not likely but one can always hope.

Any system should be watched at this time of year. Miami was hit by a system that wasn't even a depression and dropped about 15 inches of rain which caused massive flooding in Dade and Broward Counties. The NWS put out advisories early in the day and most people were sent home. Still thousands of people were stranded in there vehicles (including old Grothar)

Fastest Intensification from a Tropical Storm to a Category 5 Hurricane: 16 hours - 70 mph to 155 mph - Hurricane Wilma 2005
Maximum pressure drop in 12 hours: 90+mb - Wilma 2005
Maximum pressure drop in 24 hours: 98mb - Wilma 2005 - 1200 UTC October 18 to October 19
Fastest Intensification from a Tropical Depression to a Hurricane: 12 hours - Lorenzo 2007

Let us hope that Wilma retains her records for a considerable time into the future.

First off, you don't care what models are saying when a system doesn't exist yet, a low level center has to form first and where that starts is the key to where it goes

The latest GFS model now shows a slightly weaker system in the Gulf and much further South than the earlier models. If anyone has any questions, feel free to ask.

Say what they may, but a weakness has been left behind in the gulf, if there wasn't there wouldn't be all this convection and rain out there. Be interesting to see if this clears out quickly or not, could play a role for the imcoming system from the Carribbean? moving system farther north towards TX? there is a weakness in the gulf left behind, remains to be seen what happens....

I don't think this feature was considered when the early models were predicting development in the Bay of Campeche. I didn't when I made my posts on this on the 16th and 17th :) Wonder what effect it will have on the system.

Looks like that last northern eddy of hot water is spreading out and setting up the Atlantic for warm TS development.

expect cloud tops to cool a bit at least in the frames since after all this blow ups they go down and energy is released and of course i believe it will improve in structure by tonight but thunder storm will be limited and it may not start get goin until sunday night monday morning since wind shear will inhibit it for the moment

well to be almost exact i think it depends on the movement of the front,however if this blob detaches it self then steering currents cud take it close but i don't really see this however anyone remember Humberto the fastest strengthening i think?


Yep! Lol. The loudest,craziest wake up call I ever got. I think it did hold some kind of rapid development record. With a little more time it could've gone real bad. What the NHC says is their worst nightmare. This was another somewhat surprising storm for the area. Thank goodness for time & technology. :) Link

-sea surface temperatures were a full 2-3 degrees Fahrenheit above average in the Gulf of Mexico, with a large upper level anticyclone bringing near-zero wind shear over Audrey. This perfect recipe for rapid intensification meant that Audrey was not going to be a mere Category 2 hurricane at landfall. An additional ingredient unfavorable for intensification--the approach of a trough of low pressure with increased wind shear--would not occur in time to weaken the storm. However, the approaching trough did bring an increase in steering current winds at mid- and high levels of the atmosphere, which doubled the forward speed of Audrey overnight.
