NASA sats monitor Hurricane Olaf move into Pacific Ocean

NASA's Terra and Aqua satellites have been following Hurricane Olaf’s every move. On Oct. 19, the MODIS instrument aboard NASA's Terra satellite captured Hurricane Olaf moving into the central Pacific Ocean with a visible eye. On the same day, the Atmospheric Infrared Sounder or AIRS instrument aboard NASA's Aqua satellite gathered temperature data using infrared light. Its data showed Olaf's cloud top temperatures exceeded -63F/-53C. This indicates powerful storms with the heavy rainfall. Olaf is moving toward the west-northwest near 17 kph and the Central Pacific Hurricane Center (CPHC), who has taken over forecast responsibilities now that Olaf has crossed the 140 degree longitude line, expects Olaf to turn toward the west-northwest and then northwest by October 21.
