Cyclone Keni

Cyclone Keni reached tropical storm strength on April 8 and cyclone strength on April 9. Keni eventually became a Category 2 storm with 85 knot (98 mph) winds and brought heavy rain to Fiji. The vertical line just left of center where rainfall data seem to end is the International Date Line.

Sensing Rain Rate

Colors indicate rainfall rates based on Integrated Multi-satellitE Retrievals for the Global Precipitation Mission (GPM) (IMERG) data. Red = rates of about 5mm to 15mm/hour; green = rates of about 0.1mm to 1mm/hour. GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency.
