World weather news, October 2018

1st-3rd
A blast of unseasonably cold air led to an early-October snowstorm across southern Alberta, including Calgary. Steady snow began to fall late Monday and continued heavy at times Monday night into Tuesday across Calgary. Snow totalled 15-23 cm through mid-morning on Tuesday, and additional accumulations piled up through Tuesday night, resulting in widespread total snowfall of 25-30 cm with locally higher amounts in the mountains west of Calgary.
6th-7th
Ex-typhoon Kong-Rey became the ninth tropical system to hit Japan this year. Despite its category 5 status downgrading to tropical storm intensity before landfall, it produced damaging winds, storm surges, torrential rain and flooding across many parts of Japan and South Korea. Tracking across Japan's southern islands, it reached South Korea on Saturday, before moving north-eastwards over northern Japan on Sunday. Sustained winds of 185 km/h and wind gusts reaching 143 mph were recorded, while dumping up to 75 mm of rain an hour. The warm air associated with it exceeded Japan's highest October temperature record, reaching 36C (96.8F) in Sanjo, Niigata Prefecture.

A flash flood on the Spanish island of Majorca has killed at least 10 people, including at least three foreigners. A wave of muddy water engulfed the town of Sant Llorenc des Cardassar, in the east of the island, after heavy rain caused a river to burst its banks. Vehicles were swept away as water gushed through narrow streets. Hundreds of emergency workers and sniffer dogs are involved in the search-and-rescue effort. A five-year-old child is missing. The area was hit with more than 20 cm of rainfall in just a few hours on Tuesday, according to Spanish meteorological agency Aemet.
10th-12th
The strongest storm to hit the US in more than 25 years, and the most powerful on record in the Florida Panhandle, has headed inland after a furious onslaught that killed six people and tore apart buildings. Hurricane Michael's 250 km/h winds at landfall were only just short of category five status, making it the US's strongest storm since Hurricane Andrew ravaged southern Florida in 1992. Michael sprang quickly from a weekend tropical depression, going from a category two on Tuesday to a category four storm by the time it came ashore. Landfall happened just north of Mexico Beach, Florida, a small coastal town 25 miles (40km) east of Panama City with a population of 1,000, at about 1.30pm local time on Wednesday. According to the National Hurricane Center (NHC), the storm blew in with sustained winds of 155 mph and travelling at 14 mph. Television pictures showed broken and uprooted trees and downed power lines. Roofs were peeled away and swept into the air, and homes were split open by fallen trees. Twisted road signs lay on the ground. Palm trees whipped wildly in the winds. Louis Uccellini, the director of the National Weather Service, told CNN: "When people ...start making their assessments, they're going to realise just how powerful a category four storm can be. You're going to see a very extensive area of damaging winds all the way into central Georgia." Michael weakened to a tropical storm as it moved inland, but is on course to hit parts of Georgia, and North and South Carolina, still recovering from Hurricane Florence last month. The NHC in Miami said the eye of Michael was about 30 miles south-west of Macon in central Georgia at midnight on Thursday. The storm had sustained winds of up to 70 mph. No recorded category four storm had ever made landfall in the Panhandle, and Michael's vast size meant the effects would be felt along the coast from New Orleans to Tampa Bay, and inland as far as the Carolinas. The fast-moving tropical cyclone's outer bands were already causing torrential rain and flooding in Panama City Beach and Apalachicola by mid-morning on Wednesday. Florida authorities had warned anybody who chose not to evacuate they would be on their own, with conditions already too hazardous for emergency workers. By Friday morning, with reduced winds of 50 mph, according to the NHC, Michael had moved north-east crossing Georgia and was bringing heavy rain to North Carolina and Virginia.

Tropical cyclone Titli made landfall north of Mandasa (Andhra Pradesh, India) today in the early morning (UTC) with maximum sustained winds of 165 km/h. Heavy rainfall has affected Odisha, with Digha recording 142 mm, Balasore 109 mm, Bhubaneswar 69 mm, Puri 79 mm, and Gopalpur 75 mm over a 21-hour period.

Tornadoes and a thunderstorm supercell have swept across Queensland in Australia, injuring four people and causing widespread damage. The dangerous weather system hit the state's south-east on Thursday. One tornado struck Tansey, a town 250 km north of Brisbane, snapping trees and ripping roofs from houses. Elsewhere, four people were injured when tennis ball-sized hail shattered car windscreens, authorities said. On Thursday, large hailstones and winds gusting up to 60 mph caused extensive damage to buildings and crops. Social media users also reported injuries to animals. Almost 10,000 properties remained without power on Friday, the Australian Broadcasting Corporation reported.
