Tropical Storm Harvey Centered over Gulf of Mexico | NOAA

Aug. 29, 2017 : GOES-16 captured this geocolor image of Tropical Storm Harvey centered over the Gulf of Mexico just before 8:00 a.m. (CDT) on August 29, 2017.

As of 7:00 a.m. CDT on August 29, NOAA's National Hurricane Center reported that Harvey, was located about 90 miles east-southeast of Port O'Connor, Texas, and moving toward the north-northeast near 3 miles per hour. This motion is expected to continue throughout the morning and then a turn toward the northeast is expected later today or tonight, followed by a turn toward the north-northeast on Wednesday (8/30). On the forecast track, the center of Harvey is expected to be just offshore of the middle and upper coasts of Texas through tonight, then move inland over the northwestern Gulf coast on Wednesday. Harvey's maximum sustained winds remain near 45 mph with higher gusts. Little change in strength is forecast during the next 48 hours.

Harvey is expected to produce additional rainfall accumulations of 7 to 13 inches through Friday (9/1) over parts of the upper Texas coast into southwestern Louisiana. Isolated storm totals may reach 50 inches over the upper Texas coast, including the Houston/Galveston metropolitan area. These rains are currently producing catastrophic and life-threatening flooding over large portions of southeastern Texas and southwestern Louisiana.

Created by our partners at the Cooperative Institute for Research in the Atmosphere, the experimental geocolor imagery enhancement shown here displays geostationary satellite data in different ways depending on whether it is day or night. This image, captured as daylight moves into the area, offers a blend of both, with nighttime features on the left side of the image and daytime on the right. In nighttime imagery (seen on the left side of this image), liquid water clouds appear in shades of blue, ice clouds are grayish-white, water looks black, and land appears gray. (The city lights are a static background created with VIIRS Day/Night Band imagery from the Suomi NPP satellite. It does not show any existing power outages.) In daytime imagery (shown on the right side of the image), land and shallow-water features appear as they do in true-color imagery.
