Low-Level Water Vapor Infrared imagery (7.34 µm) from GOES-16, above, shows Hurricane Harvey developing a distinct eye shortly after sunrise on 25 August 2017 after intermittent appearances of the eye during the night. Harvey is a strong Hurricane at 950 mb (as of 700 AM CDT according to the National Hurricane Center) and is approaching the central Gulf Coast of Texas. Strong upper-level outflow to the north and then east and south is apparent in the Water Vapor animation above, and an absence of dry air near the storm portends no significant weakening before the storm reaches the Coastline. Microwave estimates of Total Precipitable Water, below, from this site, continue to show extreme moisture amounts enveloping the storm.

Visible imagery, below, from after sunrise on 25 August 2017, show a symmetric storm with a visible eye. The “Cirrus Channel” near-infrared GOES-16 Channel (1.38), bottom, shows the extensive cirrus canopy from the storm covering much of the western Gulf of Mexico and adjacent states.

For the latest information on Harvey, consult the pages of the National Hurricane Center, or the CIMSS Tropical Weather Website. In addition to the flooding threat posed from Harveywith multiple days of rain, storm surge at the coast promises considerable inundation.
