Laura Makes Landfall

Laura Makes Landfall

After making landfall near Cameron, Louisiana, as a category 4 storm, Hurricane Laura continued to move northward over western Louisiana. The Visible Infrared Imaging Radiometer Suite (VIIRS) on NOAA-20 acquired this image of Hurricane Laura at 2:50 a.m. Central Daylight Time on August 27, 2020, about two hours after the storm made landfall. Clouds are shown in infrared using brightness temperature data, which is useful for distinguishing cooler cloud structures from the warmer surface below. That data is overlaid on composite imagery of city lights from NASA’s Black Marble dataset.

Flooding in the Wake of Laura

August 29, 2020

Hurricane Laura made landfall along the Louisiana and Texas coasts on August 26, 2020. In the wake of the category 4 storm, the Operational Land Imager (OLI) on Landsat 8 acquired images showing flooded coastal lands around the towns of Cameron and Creole, Louisiana, south of the city of Lake Charles. The false-color images were acquired on August 13 and 29, 2020. They were composed from a combination of shortwave infrared, near infrared, and natural color (bands 6-5-4) to make it easier to distinguish flooded areas (navy blue and black) from drier ground. Vegetation is bright green and clouds are cyan.
