NASA finds a weak and wispy Tropical Cyclone Cebile

February 08, 2018

Vertical wind shear had already taken its toll on Tropical Cyclone Cebile when NASA's Aqua satellite passed over the Southern Pacific Ocean on Feb. 8. Cebile, now a subtropical cyclone, appeared to have wispy clouds circling it, and the storm was devoid of rainfall.

The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Aqua satellite provided a visible image of Cebile on Feb. 8 at 4:55 a.m. EST (0855 UTC). The storm is appeared as a circle of wispy clouds with the exception of at thick band of clouds in the eastern quadrant.

At 10 a.m. EST (1500 UTC) on Feb. 8, the Joint Typhoon Warning Center (JTWC) issued their final warning on the system. At that time the center of Tropical Cyclone Cebile was located near 26.3 degrees south and 76.4 degrees east, about 1,177 nautical miles south-southeast of Diego Garcia. The storm was moving toward the west at 15 mph (13 knots/24 kph). Maximum sustained winds are near 40 mph (35 knots/62 kph).

The Joint Typhoon Warning Center noted "Animated enhanced infrared satellite imagery reveals a fully exposed and decaying low level circulation center." Cebile was moving through waters too cool to maintain strength, and it was still be battered by strong vertical wind shear. The JTWC expects Cebile to dissipate by Feb. 10

#534 Bacteria are Coming for Your OJ
What makes breakfast, breakfast? Well, according to every movie and TV show we've ever seen, a big glass of orange juice is basically required. But our morning grapefruit might be in danger. Why? Citrus greening, a bacteria carried by a bug, has infected 90% of the citrus groves in Florida. It's coming for your OJ. We'll talk with University of Maryland plant virologist Anne Simon about ways to stop the citrus killer, and with science writer and journalist Maryn McKenna about why throwing antibiotics at the problem is probably not the solution.
