Mayo weather forecaster Maureen Sweeney, whose report identified a storm that could have hit the D-Day landings in the Second World War, died at the age of 100.

As The Irish Independent reports, Ms Sweeney was taking pressure and temperature readings at Blacksod lighthouse in north Mayo on June 3rd, 1944 when she reported a dramatic drop in pressure.

Her readings were passed to US General Eisenhower, who had planned D-Day for June 5th - but then delayed it based on her information.

Ms Sweeney, whose family has been closely associated with the Blacksod lighthouse, was 21 at the time.

A notice on RIP.ie says that she died “peacefully in her 101st year, surrounded by her loving family” at a nursing home in Belmullet, Co Mayo.

Her funeral mass will take place at Our Lady of Lourdes Church, Aughleam, on Friday at noon, followed by burial in Faulmore Cemetery.

About Afloat.ie – Weather

At Afloat.ie – Weather, we provide timely marine and coastal weather updates relevant to Ireland’s sailing, boating, fishing and watersports communities. The page features real-time reports, storm alerts, forecasts and climate-related developments that help readers stay informed about changing conditions around the Irish coast and offshore waters. From wind patterns and wave activity to severe weather advisories, our coverage draws on trusted sources such as Met Éireann and recognised maritime authorities.

We highlight significant events — like winter storms, heat anomalies or shifts in sea temperatures — with clear, accessible summaries and links to further detail when available. Our aim is to support safer maritime activity by sharing alerts, developments and relevant commentary as they arise. While we don’t generate forecasts in-house, we curate and reference authoritative information so users can quickly spot issues that may affect planning or navigation.

Readers turn to this section for storm warnings, weather-related incidents, research news and emerging climate impacts on Irish waters. It’s a practical resource for staying aware of conditions without claiming to replace official forecasting services.
