Florida, Kentucky USA – The National Weather Service reported a tornado briefly touched ground Thursday at about 2:30 p.m. one mile west of Miami International Airport.

The National Weather Service says two tornadoes caused damage in Kentucky on Wednesday, but no injuries were reported. The stronger tornado hit about 5 miles north-northeast of Hopkinsville in Christian County at about 4:30 p.m. CDT, causing minor damage to buildings and trees. The weather service classified it as an EF2 with 125 mph winds. Earlier, another tornado hit 5 miles southeast of Shepherdsville in Bullitt County at about 2:30 p.m. EDT. That twister was classified as an EF0, the mildest.

Serbia – The heaviest rains and floods in 120 years hit Serbia and Bosnia this week, killing three people, cutting off electricity and leaving several towns and villages isolated. Serbian power utility Elektroprivreda Srbije (EPS) said on Thursday high water levels on the Morava river have forced it to halt two hydro power plants with a combined capacity of 34 megawatts. The Serbian government has declared a state of emergency due to flash floods caused by the heavy rain throughout the country. 2 people were reported to have drowned in the floods.

Global Warming

Study: Global warming pushing hurricanes out of tropics

Tropical cyclones worldwide are moving out of the tropics and more toward the poles and generally larger populations, likely because of global warming, a surprising new study finds. Atlantic hurricanes, however, don’t follow this trend.

While other studies have looked at the strength and frequency of the storms, which are called hurricanes in North America, this is the first study that looks at where they are geographically when they peak. It found in the last 30 years, tropical cyclones, regardless of their size, are peaking 33 miles farther north each decade in the Northern Hemisphere and 38 miles farther south each decade in the Southern Hemisphere.

That means about 100 miles toward the more populous mid-latitudes since 1982, the starting date for the study released Wednesday by the journal Nature.

The trend, however, is not statistically significant in the Atlantic basin, where storms threaten the U.S. East Coast. In the Atlantic region, the study has seen a northward drift of storms of only 4 miles a decade, which just could be random.

The scientists say the changes start with man-made global warming, which alters air circulation from the tropics to just farther north and south. In the tropics, those changes increase upper atmosphere wind shifts called shear that weaken cyclone development. At higher latitudes the changes decrease the storm-decapitating shear, making those areas more favourable for storm intensification.

Environment

Global Temperature Extremes

The week’s hottest temperature was 116.6 degrees Fahrenheit (47.0 degrees Celsius) at Linguère, Senegal.

The week’s coldest temperature was minus 92.7 degrees Fahrenheit (minus 69.3 degrees Celsius) at Russia’s Vostok Antarctic research station.

Temperatures were tabulated from the more than 10,000 worldwide synoptic weather stations. The United Nations World Meteorological Organization sets the standards for weather observations, and provides a global telecommunications circuit for data distribution.

Wildfires

Wildfires – USA

The wildfires raging across Southern California have scorched more than 10,000 acres, with crews struggling to protect hundreds of homes from advancing flames.

At a news conference Thursday afternoon, officials said an 18-unit apartment complex in Carlsbad and at least seven houses had been destroyed in the more than half-dozen brush fires that have flared up in San Diego County since Wednesday.

Residents have been urged to heed evacuation orders as they come. Officials said evacuation notices covering 13,000 homes and businesses in San Marcos had been issued. Meanwhile, hundreds of people were checked into shelters, waiting for word on the status their homes.
