Tropical Storm Roke closing in on Kadena Air Base: Infrared NASA satellite imagery

Tropical Storm Roke is showing some signs of intensification on NASA infrared satellite imagery, as areas of strong convection and very cold cloud tops were spotted. Kadena Air Base in Okinawa is now in Roke's sights and should be making preparations.

NASA's Aqua satellite flew over Roke yesterday and the Atmospheric Infrared Sounder (AIRS) instrument showed powerful convection building around the storm's center and over the northern edge. Meanwhile, dry air is wrapping into the low-level center from the southwest, and limiting cloud development.

provides forecasters with an inside look into the cloud temperatures and heights, and the colder and higher the clouds go, the stronger they become. Meteorologists at the Joint use to help create their forecasts. AIRS data also showed around Roke to be near 27 degrees Celsius (81 Fahrenheit).

On Sept. 15 at 11 a.m. EDT, Tropical Storm Roke was located approximately 175 nautical miles east of Kadena Air Base, Japan, and is moving west at 6 knots (7 mph). Roke is a minimal tropical storm with maximum sustained winds near 35 mph, but expected to strengthen as it closes in on Kadena Air Base. Warm water temperatures (over 80F/26.6C) and low wind shear are allowing Roke to intensify. Tropical storm conditions are expected at the base from Friday, Sept. 16 through Sunday, Sept. 18 as Roke continues on its westward track.
