Understanding the Impact of Hurricane Helene in 2024

As Hurricane Helene approaches Florida, meteorologists warn about significant storm surge and potential flooding. The surge is expected to be particularly high in northwest Florida. Surge-related property damage is often greater than wind damage in coastal areas. Above Ground Level (AGL) refers to the point where water starts to inundate normally dry land. Storm surges and inland flooding are responsible for over 75% of tropical storm deaths, highlighting the critical importance of these factors. Helene is expected to grow unusually large due to interaction with an Upper Level Low (ULL) over St. Louis. This interaction, known as the Fujiwara Effect, will sling moisture westward. The ULL is highly unusual for this time of year and may contribute to unpredictable weather patterns. The storm's path will affect socially and economically vulnerable areas inland, with communities highlighted in yellow particularly at risk. Tomorrow evening and night pose significant threats from wind and flooding. Despite the challenges, the recent storms produced beautiful rainbows with hail and lightning.
