“A 13-state slice of the central United States from northern Michigan to southern Texas could see severe storms Sunday. The most likely area of severe weather then is an area of Moderate Risk that includes southeast Minnesota, the eastern half of Iowa, extreme northeast Missouri, west-central and southwest Wisconsin and northwest Illinois. A much larger area at Slight Risk for severe weather includes parts of South Dakota, Kansas, Oklahoma, Texas, Minnesota, Iowa, Missouri, Arkansas, Louisiana, Wisconsin, Illinois, Michigan and Indiana.” NWS reported.

More flooding reported in northern Plains and Upper Midwest, with
- 19 Major Flood sites
- 29 sites at Moderate Flooding
- 75 sites at Minor Flooding
- 135 sites are Near Flood Stage

“Critical fire weather conditions and Red Flag Warnings are in effect for today and Saturday in a 5-state portion of the southern Plains. Areas in which all outdoor burning is discourage include the eastern third of Colorado, the western third of Kansas, the Oklahoma Panhandle and western Oklahoma, the Texas Panhandle along with northwest and southwest Texas and most of new Mexico but the northwest and west-central parts of the state.” NWS reported.
In Colorado, meanwhile, wildfires have forced the evacuations of about 300 homes in the foothills west of Denver , a report said.
Weather Story: Colorado
Severe thunderstorms are expected in north central Oklahoma tonight. This area is in a tornado watch until 1 A.M. Hot, dry and windy weather is expected in western Oklahoma Saturday afternoon. The dry airmass is expected to include the western two-thirds of Oklahoma Sunday when wildfire potential will be extreme. Windy weather and relatively little rainfall will remain through next week. NWS
Tornado watches 108 and 109 issued by NWS cover 16 counties Kansas and 24 counties in Oklahoma. See report.
“Temperatures will surge into the upper 80s on Saturday afternoon along with strong southerly winds. Severe thunderstorms may develop along the dryline in central Kansas later Saturday afternoon and early evening. The main threat will be hail and winds… but a tornado or two cannot be ruled out.” NWS reported.
- Tornado severely damages homes at Pulaski: Severe damage to homes has been reported in the Pulaski and Draper areas of Pulaski County after a tornado earlier this evening, local officials and the National Weather Service said. More than 4,500 customers in Pulaski County are without power.

UK Flooding: Military Helicopters Rescue Hundreds Trapped in Homes
Military helicopters were used to rescue hundreds of people after torrential rain triggered extensive flooding to Cockermouth, Cumbria, the UK.

Heavy rain reportedly battered northern England, northwestern Wales and western Scotland last night.
The village of Seathwaite in Cumbria recorded 173mm (6.8in) of rain in 24 hours, according to the UK Met Office, wich also forecast an additional 150mm (5.9in ) for the Lake District by noon Friday.
UK’s Environment Agency had issued 6 severe flood warnings, 25 flood warnings and 51 less serious flood watches for Cumbria alone.
Several other regions in northwestern Wales, as well as in Dumfries and Galloway in Scotland, also reported flooding.
The effects of the extreme rain event were worsened by severe gales and wind gusts of 100 – 120km/h (65- 75mp) in the coastal areas and hurricane strength wind gusts of up to 153 km/h (95mph) in the mountainous regions.
Our colleagues at EDRO estimate that climate change could directly affect about half the population in the UK in the next 3 to 5 years.

What’s a Tropical cyclone?
A tropical cyclone is a storm system characterized by a low pressure center and numerous thunderstorms that produce strong winds and flooding rain. A tropical cyclone feeds on the heat released when moist air rises and the water vapor it contains condenses.
The term “tropical” refers to both the geographic origin of these systems, which form almost exclusively in tropical regions of the globe, and their formation in Maritime Tropical air masses. The term “cyclone” refers to such storms’ cyclonic nature, with counterclockwise rotation in the Northern Hemisphere and clockwise rotation in the Southern Hemisphere. Depending on their location and strength, tropical cyclones are referred to by other names, such as hurricane, typhoon, tropical storm, cyclonic storm, tropical depression and simply cyclone.
Map of the cumulative tracks of all tropical cyclones during the 1985–2005 time period.
Tropical cyclones can produce extremely powerful winds and torrential rain, as well as high waves and devastating storm surge. They develop over large bodies of warm water, and can cause significant damage to coastal regions flooding up to 40km from the coastline. Although inland regions are relatively safe from receiving strong winds, heavy rains can produce significant flooding inland. (Source)
Cyclones can relieve drought conditions
Known for devastating human populations, tropical cyclones can also relieve drought conditions. They also carry heat and energy away from the tropics and transport it towards temperate latitudes, which makes them an important part of the global atmospheric circulation mechanism. As a result, tropical cyclones help to maintain equilibrium in the Earth’s troposphere, and to maintain a relatively stable and warm temperature worldwide. (Source)
Structure of a tropical cyclone (Source: NOAA)
Tropical cyclones are areas of low atmospheric pressure near the Earth’s surface. The pressures recorded at the centers of tropical cyclones are very low. Tropical cyclones are driven by the release of large amounts of latent heat of condensation, which occurs when moist air is carried upwards and its water vapor condenses.
Eye and inner core
A strong tropical cyclone will harbor an area of sinking air at the center of circulation. If this area is strong enough, it can develop into an eye. Weather in the eye is normally calm and free of clouds, although the sea may be extremely violent. The eye is normally circular in shape, and may range in size from 3 km to 370km in diameter.

The 1970 Bhola cyclone is the deadliest tropical cyclone on record, killing more than 300,000 people and potentially as many as 1 million after striking the densely populated Ganges Delta region of Bangladesh on November 13, 1970. Its powerful storm surge was responsible for the high death toll. The North Indian cyclone basin has historically been the deadliest basin, with several cyclones since 1900 killing more than 100,000 people, all in Bangladesh. Super Typhoon Nina caused major damage and deaths in China, mainly from the collapse of the Banqiao Dam. Hundreds of thousands of people died due to the resulting floods, making it one of the deadliest tropical cyclones recorded in history. The collapse of the dam due to heavy floods also caused a string of 60 or so smaller dams to collapse. (Source)
Global Warming and Hurricanes
Source: Geophysical Fluid Dynamics Laboratory
The strongest hurricanes in the present climate may be upstaged by even more intense hurricanes over the next century as the earth’s climate is warmed by increasing levels of greenhouse gases in the atmosphere. [...]
According to a new simulation study by a group of scientists at NOAA’s Geophysical Fluid Dynamics Laboratory (GFDL), a 5-12% increase in wind speeds for the strongest hurricanes (typhoons) in the northwest tropical Pacific is projected if tropical sea surfaces warm by a little over 2°C (Figure 1). Recent preliminary findings indicate that these results may apply to the other tropical cyclone basins as well. [...] (Source: OAR NOAA)
