Ana Threatens Hawaiian Islands
Tropical storm Ana, that formed southeast of the Hawaiian islands on October 13, 2014, will be the third tropical cyclone to threaten the island chain this year. Hurricane Iselle weakened to a tropical storm and passed over the island of Hawaii on August 8, 2014. Hurricane Julio was still a hurricane when it veered to the northeast of the islands on August 10, 2014.
Tropical storm Ana was recently seen by the TRMM satellite on October 16, 2014 at 2224 UTC and October 17, 2014 at 1313 UTC. Rainfall from these two orbits are shown overlaid on GOES-WEST visible and infrared images received on the same dates at 2230 UTC and 1300 UTC respectively. The rainfall analysis from TRMM's Microwave Imager (TMI) instrument shows that Ana was very close to forming an eye, an indication that is was close to hurricane intensity, when viewed at these times.
