Sep. 11, 2018 – NASA Satellite Finds Hurricane Florence Undergoing Eyewall Replacement
NASA’s Aqua satellite provided an infrared look at powerful Hurricane Florence early on Sept. 11 that indicated it was likely undergoing eyewall replacement.
Intense hurricanes can and often undergo an eyewall replacement cycle. That happens when a new eyewall or ring of thunderstorms within the outer rain bands forms further out from the storm’s center, outside of the original eye wall. That ring of thunderstorms then begins to choke off the original eye wall, starving it of moisture and momentum. Eventually, if the cycle is completed, the original eye wall of thunderstorms dissipates and the new outer eye wall of thunderstorms contracts and replace the old eye wall. The storm’s intensity can fluctuate over this period, initially weakening as the inner eye wall dies before again strengthening as the outer eye wall contracts.
