Claims circulating on social media suggested that after Iran bombed a cloud-seeding facility in the UAE, Tehran experienced a sudden temperature drop and snowfall. However, experts have stated that there is no evidence to support the notion that such an attack occurred or that it could influence weather patterns across borders.
By Wednesday night, most parts of Los Angeles have a roughly 20% to 30% chance of getting a measurable amount of rain. Winds are expected to pick up late Wednesday into Thursday, especially in mountain and desert areas, with gusts in the 25- to 35-mph range.
The first tornado touched down near Biola as an EF-0 at 2:10 p.m and lasted two minutes. The tornado's estimated wind peak was 70 mph, and its path length was 50 yards, while its width was 5 yards.
"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."
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.
"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.
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.
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.
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.
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.
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.
The threat of flooding is set to peak this morning, with road networks expected to bear the brunt of the deluge. However, damage to residential and commercial properties is also likely, emergency services have warned. With Dublin, Louth, Waterford and Wexford under Status Orange rain warnings, people in those counties have been urged to work from home in order to keep the roads clear for emergency vehicles.
The sun is putting on a show. On Sunday the star unleashed several strong and bright solar flares, including one of the most powerful eruptions seen in decades. Far from the steadily glowing orb we sometimes picture, the sun's surface is made up of roiling plasma thrown about by twisting magnetic fields. When these fields snap, they can throw out huge bursts of energy and charged particles into spacea solar flare.
Along coastlines, where tides are typically magnified, they profoundly affect navigation, commerce, coastal flooding, water properties and sediment transport. Tides impact the flooding of rivers and, thus, influence the extent of their floodplain, which has cascading effects on biogeochemical and ecological processes.
