Kennedy predicts hot and dry conditions from the west will shift eastward later this week, allowing for a noticeable warm-up and shift towards spring-like conditions.
"This is going to help fill that gap in minutes to hours lead time that's vital to know where the heaviest rain is going to hit," Ralph said. "And when and what communities are going to be affected so people in the preparedness community and water resource management community can take action to help protect people's lives and property."
"These improvements empower communities to prepare earlier and more effectively for dangerous hazards from tropical storms and hurricanes," said Michael Brennan, director of NOAA's National Hurricane Center.
The storm from Sunday into Monday has the potential to become a bomb cyclone, which occurs when central pressure drops at least 0.71 inches of mercury (24 millibars) in 24 hours or less. That rapid strengthening would generate an expansive and intense wind field.
While humans have assembled a lot of weather data, flash floods are too short-lived and localized to be measured comprehensively, the way the temperature or even river flows are monitored over time. That data gap means that deep learning models, which are increasingly capable of forecasting the weather, aren't able to predict flash floods.
Met Éireann is progressing in the area of more localised weather warnings, via the use of polygons to represent areas under warnings. This will mean a move away from county-based warnings to a sub-county-based warning approach, which will identify where the expected impacts will be in the county.
Britain is about to be hit with showers of 'blood rain', according to experts from the Copernicus Atmosphere Monitoring Service (CAMS). This is thanks to a plume of red Saharan dust, which is currently sweeping over Europe towards the UK. When this dust mixes with Britain's persistent rain, the precipitation will take on a distinctive reddish colour - creating a phenomenon known as 'blood rain'.
In November 2025, a massive storm rolled across the lower Mekong River delta, dumping multiple inches of rain onto the wide, flat river plain that covers much of Cambodia. The river rose and rose. The force of the water churned up mud from the river bottom. The muddy water flowed downstream and rushed into the many farming and fishing towns that line the Mekong's banks.
When I spoke with emergency management officials last year, they all mentioned the same frustrating scenario. People ignore storm warnings until the precipitation starts falling, then suddenly everyone rushes out at once. The roads become congested with anxious drivers, accidents spike, and stores run out of essentials just when people need them most. But here's what really gets meteorologists worked up about this pattern. Modern weather forecasting has become incredibly accurate, especially for major winter storms.
Wexford, Wicklow, Dublin, Meath and Louth will be under a Status Yellow wind warning and Met Éireann are warning of fallen trees and loose debris, as well as difficult travelling conditions associated with this warning. Counties Cork, Waterford, Carlow, Kilkenny, Wexford, Wicklow, and Dublin will be under also be under a Status Yellow rain warning and these counties can expect flooding, poor visibility and difficult travel conditions for the 24-hour period.
"It will prove cold with some frost and ice in places on Friday morning, especially in the west and north," she said. "Munster and south Leinster will see cloud, but that will clear to leave dry and sunny conditions with a few isolated showers in the north and highest temperatures of 3C to 7C," she said. Friday night will prove mainly dry but very cold and frosty with some icy patches.
