Dr. Jeff Masters’ WunderBlog : Typhoon Utor Pounds Phiippines, Heads for China | Weather Underground

Typhoon Utor Pounds Phiippines, Heads for China

Posted by: Dr. Jeff Masters, 1:51 PM GMT on August 12, 2013 +52

Typhoon Utor powered ashore on the northern Philippine Island of Luzon on Monday near 3 am local time (3 pm EDT Sunday) as a Category 4 storm with 140 mph winds. Damage was heavy in Casiguran(population 24,000) near where the typhoon made landfall, with 80% of the infrastructure of the town reportedly destroyed, and all roads into the city blocked. Utor is being blamed for two deaths so far, and 44 fishermen are reported as missing.

Passage over Luzon disrupted the inner core of Utor, reducing the storm to Category 2 strength with winds of 100 mph. Satellite imagery shows that the typhoon is re-organizing, and a new eyewall is forming. Ocean temperatures are very warm, about 30°C (86°F), which is approximately 0.5 – 1.0°C above average.These warm watersextend to tremendous depth, giving Utor a huge source of energy to tap into. Wind shear is low, 5 – 10 knots. These favorable conditions for intensification will last until the typhoon gets midway between the Philippines and China, where wind shear will rise to the moderate range and ocean waters will cool to 29°C with a much lower heat content. I expect Utor will intensify into a Category 3 storm today, and make landfall in China as a Category 2 or 3 storm about 200 hundred miles southwest of Hong Kong about 06 UTC on Wednesday. Utor is a very wet storm, and will likely bring a large swath of 8+ inches of rain across Southeast China on Wednesday. These rains will cause dangerous flash flooding and mudslides.

Utor is a Marshallese word for squall line, andhas been used for three tropical cyclones in the Western Pacific–in 2001, 2006, and 2013. Utor reached super typhoon status with 150 mph winds on Sunday, making it the strongest tropical cyclone globally so far in 2013. Earth’s previous most powerful tropical cyclone of 2013 was Typhoon Soulik,which reached Category 4 strength with 145 mph winds on July 10. Soulik weakened to a Category 2 storm before hitting Taiwan on July 12.

Dr. Jeff Masters’ WunderBlog : Austria and Slovenia Set All-time Heat Records; Record Heat in Shanghai, China | Weather Underground

A historic heat wave is underway in Central Europe, where both both Austria and Slovenia set all-time national heat records on August 8. Three locations in Austria passed the 40°C (104°F) mark, beating the former national record of 39.9°C (103.8°F) set just last week, on August 3rd at Dellach im Drautal. The hottest spot today (yet to be officially confirmed), was Neusiedl/See, with a 40.6°C (105.1°F) reading. Slovenia also surpassed its national heat record on August 8, with a 40.8°C (105.4°F) reading at Cerklje ob Krki (former record: 40.6°C (105.1°F) at Crnomelj on July 5, 1950.) Ljubljana, the capital of Slovenia, has broken its all-time heat record five of the past six days, with each day hotter than the previous record. The newest record is the 40.2°C (104.4°) recorded on August 8th. Records go back 150 years at this station.

Remarkable heat in East Asia
China’s most populous city, Shanghai, broke its all-time record for hottest temperature on record for the second time this summer on August 7, when the mercury topped out at 40.8°C (105.4°F). The previous record was set just the day before (40.6°C/105.1°F), and also on July 26th. Prior to this summer, the record for Shanghai was 40.2°C (104.4°F) during the summer of 1934. Records in Shanghai date back to 1872. Today (August 8th), the temperature peaked at 40.2°C (104.4°F), so Shanghai has had its four hottest days in its history this summer. Extreme heat was also experienced over South Korea and Japan today, and wunderground’s weather historian Christopher C. Burt has the details in his latest post. Many more all-time heat records may have fallen in both Central Europe and East Asia, and Chris plans to update his post with all the latest records on Friday.

Extensive credit for researching these records goes to weather records researcher Maximiliano Herrera, who maintains acomprehensive set of extreme temperature records on his web site.
