NASA satellite imagery shows the impact of hurricane Florence

Hurricane Florence has ravaged the states of Carolina and caused widespread damage to property which is estimated to be worth somewhere between $17 billion and $22 billion. Moody’s Analytics has called Florence as among the 10 costliest hurricanes. A large number of people too have been displaced from their homes and rendered homeless. relief agencies and government organizations are active on the ground to provide help.

NASA has released high-resolution satellite images of the impact of hurricane Florence over one week. Let’s have a look at the NASA images. NASA data and researchers observed and analyzed the event, providing a steady stream of information to the Federal Emergency Management Agency (FEMA) and the National Guard to help assess the hurricane’s impact.

NASA’s Aqua satellite also offers an infrared look at fading Post-Tropical Cyclone Florence’s clouds, identifying where the strongest thunderstorms were located. Those strong thunderstorms spanned from the Mid-Atlantic to New England.

NASA’s IMERG estimated Florence’s rainfall from Sept. 10 to 17, 2018. IMERG estimates show on the order of 250 mm of rain (~10 inches, shown in red) or more reaching inland over most of central and southern No. Carolina as well as the northeast corner of So. Carolina.
