This infrared imagery from GOES-16 shows the path and dissipation of Hurricane Harvey into a tropical storm during a more than 60-hour period beginning at about 8:00 pm (EDT) on August 24, 2017, and ending at noon today, August 28.
At 1:00 pm CDT, NOAA’s National Hurricane Center reported that Tropical Storm Harvey is about 40 miles east-northeast of Port O’Connor, Texas, and drifting erratically toward the east-southeast. A slow motion toward the southeast is expected later today through tonight and a gradual turn toward the northeast and a continued slow forward speed are expected Tuesday and Tuesday night (8/29). The center of Harvey is expected to be just offshore of the middle and upper coasts of Texas through Tuesday night. Harvey’s maximum sustained winds are near 40 mph (65 km/h) with higher gusts and forecasters say some slow intensification is possible during the next 48 hours.
Harvey is expected to produce additional rainfall accumulations of 15 to 25 inches through Friday over the upper Texas coast and 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. Elsewhere, Harvey is expected to produce total rain accumulations of 5 to 15 inches farther south into the middle Texas coast and farther east across south-central Louisiana. Rainfall amounts of 5 to 10 inches are expected in southeast Louisiana.
This loop was created with Band-13, one of the new spectral bands offered by GOES-16’s Advanced Baseline Imager. Band-13, the so-called “clean” longwave infrared band, is primarily used to monitor cloud characteristics, such as cloud top temperature (shown in green/yellow/red), which is associated with storm intensity.
