World weather news, September 2015

In Fairbanks, Alaska, winter arrived early with a blanket of snow. On average Fairbanks gets about 5 cm of snow in September; today more than 15 cm was measured at Fairbanks International Airport, making the third heaviest September snow-day on record. Wintry weather looks set to continue in Alaska, with up to 30 cm of snow forecast for this week.
Taiwan faces a big clear-up after Typhoon Dujuan, which killed at least two people, injured more than 300, displaced thousands and left nearly half a million without power. On Monday night Dujuan made landfall in north Taiwan with wind speeds exceeding 150 mph along the island's east coast. It was accompanied by torrential rain triggering multiple landslides. The heaviest rain was in north-east Taiwan in the mountainous Wulai district where more than 90 cm fell - nearly a third of the country's annual rainfall. Dujuan is the 21st typhoon of the season. It developed from a tropical depression to a category 4 typhoon before it reached Taiwan, where it weakened, becoming a tropical cyclone as it moved into mainland China.
A severe thunderstorm hit Brisbane, Australia. It had moved towards the coast bringing with it 10,000 lightning strikes that hit the city in less than two hours. The storm moved across the city in the afternoon producing dark skies, hammering hail, torrential rain and gusty winds, and cutting the power to more than 4,500 properties, as well as causing flight delays and road accidents.
For the second time in less than a week, Fairbanks, Alaska, was blanketed with heavy snow. This time, it was a record-breaker. Officially, 11.2 inches of snow blanketed Fairbanks International Airport, setting an all-time September daily snow record, previously 7.8 inches on 13 September 1992. This also topped the previous record for any 24-hour September snowfall of 9 inches in 1992, according to Rick Thoman from the National Weather Service in Fairbanks. Records in Fairbanks date to 1904.
The summerlike temperatures that continued well beyond August will result in the warmest September on record for many locations across the Midwest and the Northeast. In New York City's Central Park, the average temperature through to the 29th was 74.6F, nearly a full degree (F) above the record month in 1961, where the average temperature was 73.5F. Record-challenging temperatures extend as far west as Minneapolis, where the average temperature in the same period was slightly below the warmest September ever (in 1897) at 68.8 F. The warmest September on record for Pittsburgh was in 1881, when the average temperature throughout the month was 77.3 F. This September is likely to be the warmest since 1931. Through to the 29th, the average temperature in Pittsburgh has been warmer than that, at 70.0 F, about 5.6 degF above normal for the month. Dozens of locations, including Boston, Hartford (Connecticut) and Burlington (Vermont) will have their warmest September on record this month. Many of these records date back to the early 1900s and a few go back to the late 1800s.
September the coolest since 2001 in de Bilt (The Netherlands); the mean temperature of 13.4C was 1.1 degC below the 1981-2010 average. In Germany a hot and dry August was followed by a normal September, temperature-wise.
Hurricane Joaquin grew into a category-three storm late in the day as it approached the central islands of the Bahamas on a projected track that would take it near the US east coast by the weekend. Maximum sustained winds reached 185 km/h and the hurricane-strength winds extended 55 km from the centre of the storm over the Atlantic ocean, said the US National Hurricane Center in Miami, which predicted Joaquin would develop into a major hurricane in the coming days.
