Federal forecasters say El Niño is likely to develop this summer and persist through the rest of the year, a shift that typically nudges global temperatures higher and reshapes rainfall, drought and storm patterns in different regions.

Honolulu officials have ordered the closure of non-essential city offices and a range of public facilities as severe weather approaches Oʻahu, while activating the Emergency Operations Center and preparing emergency shelters for residents and visitors.

Daylight saving time returns this weekend, bringing a sudden one-hour shift that can disrupt sleep and daily routines. Here are practical, low-stress steps to prepare in the days before the change and to help your body adapt afterward—especially for households with children or pets.

UN agencies say back-to-back tropical storms and monsoon-related rainfall have triggered record-breaking floods across parts of southeast Asia, causing widespread deaths, displacement and damage, while warming temperatures raise the risk of more extreme rainfall.

After multiple days of potential severe weather in the Central U.S., forecasters are watching Friday for a potentially significant setup as a dipping jet stream aligns with a developing low pressure system, increasing wind shear while a cold front and warm, moist air combine to boost instability.

Warmer air is spreading across much of the South, but winter is lingering across northern parts of the U.S. Light snow and a risk of ice are possible from the Ohio Valley to the Appalachians and into parts of the mid-Atlantic, with additional rounds of snow and some ice expected later in the week for portions of the Northeast and New England.

A cold front is moving through the D.C. region, bringing a sharp temperature drop, overnight freezes, and a chance of light snow and a wintry mix early in the week. While significant accumulation is not expected, a brief period of snow and freezing rain could create slick spots, especially Tuesday morning, before conditions transition to plain rain and a milder, unsettled pattern later in the week.

Spring feels like a clear turning point after winter, but its official start depends on whether you use the meteorological calendar or the astronomical one. Here’s how each definition works, why the dates differ, and what changes people typically notice across the UK as the season gets underway.

Even as a major winter storm pulls into the Canadian Maritimes, forecasters say the Northeast should prepare for additional rounds of wintry weather, including a clipper system and a later-week storm with uncertain track and precipitation types.

NOAA’s Storm Prediction Center is adding “Conditional Intensity” to its Convective Outlooks in March 2026, giving emergency managers and the public a new way to distinguish between days with widespread severe weather and days when fewer storms could still produce more extreme impacts.
