D-Day Weather Forecaster Maureen Sweeney Dies at 100

Sweeney's Critical Weather Reports Led to the Successful Delay of D-Day Invasion

Maureen Sweeney, the Irish postmistress whose weather reports led to the delay of D-Day, has died at the age of 100.
Sweeney and her husband Ted worked at the Blacksod Lighthouse, a coast guard and weather station, where they took hourly barometer readings.
On June 3, 1944, Sweeney forecasted an impending storm approaching from the Atlantic, leading to the postponement of the D-Day invasion from June 5 to June 6.
Despite Ireland's official neutrality during World War II, the Irish Meteorological Service shared their information with the Allies.
In 2021, Sweeney was awarded a special U.S. House of Representatives honor for her role in the D-Day invasion.
