Tropical Storm Vance is maintaining a northward track over the eastern Pacific, with heavy rainfall and dangerous surf expected along parts of western Mexico. In its 2 a.m. MDT advisory Wednesday, Oct. 28, the U.S. National Hurricane Center places Vance about 455 kilometres west of Manzanillo and 365 kilometres southwest of Cabo Corrientes, Mexico. The storm has maximum sustained winds of 65 km/h and is moving north at 19 km/h. A turn toward the north-northeast is expected la

A severe thunderstorm produces weather capable of causing significant damage, injury, or dangerous conditions. Thunder and lightning alone do not make a storm severe. In Canada, the main criteria are: Large hail: hail 2 cm or larger in diameter. Damaging winds: wind gusts of 90 km/h or stronger. Tornadoes: any confirmed or suspected tornado makes the storm severe. Other significant impacts: Environment and Climate Change Canada can issue warnings based on particularly dangero

A powerful earthquake has struck southwestern China. The magnitude 7.0 earthquake occurred at 10:33 p.m. local time and was centred 183.4 km east-northeast of Nagqu, China. It was at a depth of 10 kilometres. Hundreds of homes collapsed, and at least 16 people have been killed. The earthquake was also felt in India and Myanmar (Burma). Western China is one of the most geologically active parts of the world, particularly when it comes to earthquakes.

Subtropical Storm Josephine is accelerating northeastward away from the United States and is expected to become a powerful extratropical cyclone with hurricane-force winds by early Friday. Josephine is about 765 kilometres south-southwest of Halifax, Nova Scotia. The storm has maximum sustained winds of 100 km/h, with higher gusts, and is moving northeast at 20 km/h. Some additional strengthening is forecast through Thursday as the system transitions into an extratropical cyc

Hurricane strength is measured using the Saffir-Simpson Hurricane Wind Scale, which classifies hurricanes based on their maximum sustained wind speeds. The scale ranges from Category 1 to Category 5. A hurricane becomes Category 1 when sustained winds reach at least 119 km/h. Category 1 hurricanes have winds of 119 to 153 km/h, while Category 2 storms have winds between 154 and 177 km/h. A hurricane reaches Category 3 at 178 km/h and is considered a major hurricane. Category

A storm-force low-pressure system off the coast of North Carolina could gradually develop subtropical or tropical characteristics over the next several days, according to the U.S. National Hurricane Center. The system, designated AL93, remains attached to an occluded frontal boundary a few hundred miles offshore. It is expected to move slowly north-northeastward over the Gulf Stream, potentially developing more organized thunderstorm activity as it gradually loses its frontal
