The tropical cyclone has intensified in the last 24 hours from Category 1 on the Sapphire-Simpson hurricane scale. Wind speeds range from 130 kilometers per hour to 250 kilometers per hour (80-155 miles per hour).
The scale used by Australia, Fiji and other countries in the South Pacific is slightly lower than that of the Sapphire-Simpson, and Yasa has already been classified into a Category 5 category.
Yasa may strengthen further in the next 12 hours before it weakens slightly when it reaches Fiji in about 12 hours. However, the storm is still expected to be strong when it reaches the country on Thursday night (Thursday morning ET) local time.
In addition to winds of up to 200 km / h (125 mph), the storm will receive more than 250 mm (10 inches) of rain, which can cause flooding and landslides. The intensity of the storm can cause very rough seas and flooding of low-lying coastal areas.
The NAAA warns that even well-built homes will face “heavy damage” as a result of winds blowing at speeds of up to 200 kilometers per hour, while trees and power poles will fall down and cause further damage and disruption.
While Yasa was affecting Fiji, another tropical cyclone, Sasuke, passed north of Tonga but had no effect on the islands.
Sasuke is the equivalent of a 100-kilometer (62-mile) strong tropical storm. No additional landmasses are in its path and the storm is expected to melt in the next day or two.
With each additional measure of average global warming, the rate and frequency of wildfires will increase significantly, as will the intensity of tropical cyclones that lead to heat, ”Bainimarama said.
