Cyclone Debbie Made Landfall in Australia

A powerful cyclone came ashore on Australia’s northeastern coast on Tuesday, the most intense storm to strike the country in several years. Cyclone Debbie made landfall on the Queensland coast south of the town of Bowen, which lies about 300 miles southeast of Cairns. The storm hit land with winds in excess of 120 mph, which would make it the equivalent of a major hurricane on the Saffir-Simpson Hurricane Wind Scale used in the United States. Debbie stands out as an intense storm in an unusually quiet cyclone season in this part of the world. A storm of this magnitude hasn’t struck the country since Cyclone Yasi made landfall south of Cairns in February 2011.

Cyclone Debbie made landfall in an area that’s home to nearly 100,000 people, including the towns of Mackay and Bowen. Media reports indicate that local emergency response crews were worried that the town of Bowen, which found itself in the cyclone’s eyewall, would sustain substantial damage from the storm, as many of the town’s homes and businesses were built before more stringent construction standards were introduced in the 1980s [PDF]. The town of Mackay and its suburbs saw less intense winds from the cyclone, but residents along the coast were ordered to evacuate in anticipation of a dangerous storm surge.

Early reports of damage are few and far between, due to power and communications outages with the hardest-hit areas. Videos published online by storm chasers in the area show damage to trees and buildings as the storm came ashore.

Cyclone Debbie formed under ideal conditions that allowed the storm to thrive. Sea surface temperatures off the northeastern Australian coast were around 80°F, there was ample tropical moisture to feed the storm, and the cyclone encountered almost no wind shear in the upper levels of the atmosphere to disrupt its development. The storm took advantage of the favorable conditions and underwent rapid intensification as it neared the Australian coast early on Tuesday morning local time. WeatherBELL’s Ryan Maue reported that satellite estimates pegged the cyclone’s peak winds at more than 140 mph at the storm’s strongest point. The storm weakened somewhat as it approached the coast due to an eyewall replacement cycle, a common process in strong tropical cyclones in which a new eyewall develops and chokes off the old eyewall, temporarily weakening the storm until the process is completed.

Tropical cyclones in the southwestern Pacific Ocean are most common between the months of November and April, though cyclones are possible at any point in the year. The peak of the season coincides with the heat of the summer toward the beginning of the year. Australia’s northern coast is vulnerable to major tropical cyclones. The last significant cyclone to strike this region of Queensland was Cyclone Marcia in 2015; the storm caused significant damage but thankfully resulted in no fatalities. Debbie threatens to be the strongest storm to make landfall since Yasi back in February 2011. Cyclone Yasi reached shore with winds of 155 mph, causing billions of dollars in damage.

The term “tropical cyclone” applies to any low-pressure system that develops over the ocean and feeds its energy off of thunderstorms near the center of the system rather than winds high in the atmosphere. Strong tropical cyclones are called “hurricanes” in the Atlantic and eastern Pacific Ocean, “typhoons” in the northwestern Pacific Ocean, and simply “cyclones” everywhere else in the world, including around Australia. All of the storms are structurally the same—the only difference is that they’re classified a little differently based on wind speeds.

It's So Cold In One Part of Russia That People's Eyelashes Are Freezing

Oymyakon, a rural village in the eastern Russian region of Yakutia, is one of the coldest inhabited spots in the world. While some schools in the U.S. cancel classes as temperatures approach zero, schools in Oymyakon remain open in -40°F weather. But recently temperatures in the region have dropped too low even for seasoned locals to handle. As AP reports, the chill, which hit -88.6°F on January 16, is cold enough to break thermometers and freeze eyelashes.

Photos shared by residents on social media show the mercury in thermometers hovering at -70°F, the lowest temperature some are built to measure. When thermometers fail, people in Oymyakon have other ways of gauging the cold. Their uncovered eyelashes can freeze upon stepping outside. Hot water tossed in the air will also turn to snow before hitting the ground.

To Oymyakon's 500-odd citizens, the most recent cold snap is nothing out of the ordinary. Temperatures are perpetually below freezing there from late October to mid-May, and average temperatures for the winter months frequently reach −58 °F. On Tuesday, residents were advised to stay inside and stay as warm as possible. Of course, that directive wasn't enough to stop some adventurous locals from sneaking outside for selfies.

Heated Mats Keep Steps Ice-Free in the Winter

The first snow of the season is always exciting, but the magic can quickly run out when you remember all the hazards that come with icy conditions. Along with heating bills, frosted cars, and other pains, the ground develops a coat of ice that can be dangerous for pedestrians and drivers alike. Outdoor steps become particularly treacherous and many people find themselves clutching their railings for fear of making it to the bottom headfirst. Instead of putting salt down the next time it snows, consider a less messy approach: heated mats that quickly melt the ice away.

The handy devices are made with a thermoplastic material and can melt two inches of snow per hour. They're designed to be left outside, so you can keep them ready to go for the whole winter. The 10-by-30-inch mats fit on most standard steps and come with grips to help prevent slipping. A waterproof connector cable connects to additional mats so up to 15 steps can be covered.

Unfortunately, this convenience comes at a price: You need to buy a 120-volt power unit for them to work, and each mat is sold separately. Running at $60 a mat, the price can add up pretty quickly. Still, if you live in a colder place where it's pretty much always snowing, it might be worth it.
