USGS Tracks How Hurricane Floodwaters Spread Non-Native Freshwater Plants and Animals

Hurricanes Harvey, Irma, Maria, and Nate may have spread non-native freshwater plants and animals into new water bodies, where some of them can disrupt living communities or change the landscape. Storm surges and floodwaters can quickly spread non-native aquatic species into waterways where they weren’t found before. They can even create temporary freshwater zones in saltwater environments

Cyclone Marcus

It is the first category 5 cyclone of 2018 and the strongest to hit Darwin, Australia, since 1974. But so far, Cyclone Marcus has directed most of its fury into the Indian Ocean, rather than onto landmasses.

Typhoon Lan

With Lan churning over warm water, and with upper level winds staying relatively calm, forecasters believe the storm could undergo rapid intensification and reach category 4 strength on October 20 or 21. The storm is expected to pass east of Okinawa on October 22 and make a possible landfall near Tokyo on October 22 or 23.
