MARCH 2021


Severe weather produced a deadly and damaging start to meteorological spring in the Atlanta area on the 1st). From Sunday afternoon through early Monday, downpours and strong thunderstorms erupted across parts of the Tennessee Valley and the Southeast. More than two dozen wind damage reports came in across the states of Arkansas, Tennessee, northern Mississippi and Alabama, and Georgia. On Monday, a severe storm moving through northern Georgia spawned a tornado around 6 a.m. EST. The damage was surveyed by the National Weather Service on Monday afternoon, which confirmed the tornado as an EF1 on the Enhanced Fujita Scale. Despite the damage, no injuries or fatalities were reported from the tornado. However, strong wind gusts caused tree branches to crash down nearby, which led to one fatality in the metro Atlanta area.

Emergency evacuations have been ordered for residents in the Haiku area in Maui, Hawaii, after heavy rainfall has caused a breach on the Kaupakalua Dam on the 8th.

The Maui Fire Department said it received more than a dozen calls for assistance. Mayor Michael Victorino surveyed the flooding and reported that Kaupakalua Road was impassable in some areas. At least six homes were heavily damaged or destroyed. After a breach was confirmed on the Kaupakalua Dam on Monday afternoon, Victorino urged people to evacuate from the Haiku area.
