GOES-16 Sees Lightning from Hurricane Harvey
GOES-16 captured this animation of Hurricane Harvey showing cloud cover and optical lightning emissions on August 25-26, 2017. This loop was created by combining infrared imagery from GOES-16's Advanced Baseline Imager, which is useful for determining the cloud features both day and night, with imagery from the satellite's Geostationary Lightning Mapper, which observes total lightning (both in-cloud and cloud-to-ground) day and night across the Western Hemisphere. Forecasters can use this kind of imagery depicting both cloud cover and lightning flashes to get a better sense of storm intensification and thunderstorm severity during dangerous weather conditions.
Harvey's Remnants Move to the Northeast
GOES-16 captured this geocolor image of Tropical Depression Harvey at about 7:20 am CDT today, August 31, 2017. At 4:00 am CDT, NOAA's National Hurricane Center reported that Harvey would be over northwestern Mississippi by this afternoon, the western Tennessee Valley region on Friday (9/1), and into the lower Ohio Valley early Saturday (9/2). The storm is expected to dissipate by Saturday afternoon.
Harvey Moves Farther Inland
GOES-16 captured this geocolor imagery of Tropical Storm Harvey moving farther inland this afternoon, August 30, 2017. At 1:00 pm CDT, NOAA's National Hurricane Center reported that Harvey's maximum sustained winds have decreased to near 40 mph with higher gusts. Additional weakening is forecast during the next 48 hours as the storm moves farther inland, and the cyclone is expected to weaken to a tropical depression tonight. Created by our partners at the Cooperative Institute for Research in the Atmosphere, this daytime geocolor imagery shows land and shallow-water features similar to how they would appear in true-color imagery.
Harvey Makes Landfall Near Cameron, LA
This GOES-16 infrared animation shows Tropical Storm Harvey making landfall just west of Cameron, Louisiana, at approximately 4:00 am CDT this morning, August 30, 2017. At 7:00 am CDT, NOAA's National Hurricane Center reported that Harvey's maximum sustained winds are near 45 mph with higher gusts. Gradual weakening is forecast as the center of the storm moves farther inland, and Harvey is expected to become a tropical depression by tonight. This loop was created with Band-13, which is primarily used to monitor clouds and storm intensity, shown here by the green, yellow and red colors of the cloud tops. In general, the brighter colors indicate more intense areas of the storm system.
Intense Storms Continue in the Houston Area
As seen in this one-minute visible imagery captured by GOES-16 earlier today, August 29, 2017, Tropical Storm Harvey continues to deliver intense rainstorms in the Houston area. Note the rough and bubbling cloud tops to the northeast of Galveston Bay. As of 10:00 am (CDT) on August 29, 2017, NOAA's National Hurricane Center reported that 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 early Wednesday (8/30). Harvey's maximum sustained winds remain near 45 mph with higher gusts. No significant change in strength is expected before the center moves inland. A gradual weakening should begin thereafter.
