Cyclone Evan is one of the strongest cyclones to affect Fiji in almost two decades, and NASA satellites are analyzing the storm and providing data on rainfall, cloud height, temperature data and more to forecasters.

On Monday, Dec. 17 many warnings and watches were in effect. A tropical cyclone warning is in effect for Fiji. A Hurricane warning is in effect for the Mamanuca island group, west of the line from Lautoka to Sigatoka and nearby smaller islands.

A gale warning is posted for the Lomaiviti group, rest of Viti Levu and nearby smaller islands, Kadavu, Beqa, and nearby smaller islands. There are also other local warnings in effect for Fiji.
The Joint Typhoon Warning Center (JTWC) is issuing forecasts for Evan and is using NASA and other satellite data to provide warnings and status updates on the storm. On Dec. 17 at 0900 UTC (4 a.m. EST), Cyclone Evan had maximum sustained winds near 115 knots (132 mph/213 kph). Evan is a Category 4 cyclone on the Saffir-Simpson Scale.
