Hurricane Ivo Continues Its Northward Trek



Hurricane Ivo, which at 11 a.m. EDT on Friday, Sept. 21 was a Category One storm with maximum sustained winds of 65 knots (75 miles per hour), continues to move north toward Baja, Calif., in this infrared image from the Atmospheric Infrared Sounder instrument on NASA's Aqua satellite. Ivo is expected to weaken to a tropical storm later today and make landfall in Baja, Calif., as a tropical storm some time on Monday, Sept. 24. The image, acquired at 5 a.m. EDT Sept. 21, shows large areas of strong convection surrounding the core of the storm (in purple).

Ivo Heads North To Baja



Hurricane Ivo is seen in this infrared image acquired by the Atmospheric Infrared Sounder instrument on NASA's Aqua satellite at about 5 p.m. EDT Sept. 21, when the storm was a Category One hurricane with maximum sustained winds of 70 knots (80 miles per hour). The storm is currently moving north-northwest toward Baja, Calif., at six knots (seven miles per hour). This AIRS image shows the temperature of the cloud tops or the surface of the Earth in cloud-free regions. The lowest temperatures (in purple) are associated with high, cold cloud tops that make up the top of the storm. The infrared signal does not penetrate through clouds. Where there are no clouds the AIRS instrument reads the infrared signal from the surface of the Earth, revealing warmer temperatures (red). This infrared image shows large areas of strong convection surrounding the core of the storm (in purple).

Tropical Storm Ivo churns in the eastern Pacific



Tropical Storm Ivo churns in the eastern Pacific south of Baja, Calif., in this satellite image created by data from the Atmospheric Infrared Sounder (AIRS) on NASA's Aqua satellite in the early morning hours of Sept. 19. As of 11 a.m. EDT Sept. 19, Ivo had sustained winds of 55 knots (63 miles per hour). The blue area shows clouds and rains. This AIRS image shows the temperature of the cloud tops or the surface of the Earth in cloud-free regions. The lowest temperatures (in purple) are associated with high, cold cloud tops that make up the top of the typhoon. The infrared signal does not penetrate through clouds. Where there are no clouds the AIRS instrument reads the infrared signal from the surface of the Earth, revealing warmer temperatures (red). This infrared image shows large areas of strong convection surrounding the core of the storm (in purple).
