Hurricane Darby off the Pacific Coast of Mexico



Washington, DC, United States

Hurricane Darby as observed by the Atmospheric Infrared Sounder AIRS onboard NASA Aqua in July, 2004. This daylight image of Hurricane Darby on July 28 was made with the visible sensor in the AIRS instrument suite. After reaching sustained winds on July 27 of 100 knots (115 mph) with gusts to 120 knots (138 mph), the intensity of the storm is now lowered to 75 knots (86 mph). Located in the eastern north Pacific Ocean located about 1,165 miles west-southwest of the southern tip of Baja California, the storm continues its west/northwest path at 14 knots (16mph). Figure 1 is a daylight snapshot from AIRS visible/near-infrared sensor before Darby became a tropical storm. Darby is in the upper right-hand corner. Circulation is not apparent because the storm was not organized sufficiently to allow the nascent eye to appear. At this time, winds were approximately 35 mph. Figure 2 is an AIRS infrared image. Darby falls on the edge of two AIRS data granules, which have been "stitched" together in this image. Storm intensity is lowered to 75 knots (86 mph), down from 100 knots (115 mph).
