Federal forecasters say El Niño is likely to develop this summer and persist through the rest of the year, a shift that can elevate global temperatures and reshape regional weather patterns, including rainfall, drought risk, and storm behavior.

Honolulu officials have ordered the closure of non-essential city offices and announced widespread park and campground suspensions as severe weather threatens Oʻahu. The City will open seven emergency shelters and is urging residents and visitors to limit travel, stay informed, and prepare for transportation disruptions.

Daylight saving time returns in March, bringing a one-hour shift that can disrupt sleep and daily routines. Practical steps—starting in the week before the change—can help adults, children, and pets adapt more smoothly.

UN agencies say back-to-back tropical storms and monsoon-related rainfall have triggered record-breaking floods across parts of Southeast Asia, causing hundreds of deaths, mass displacement and growing humanitarian needs, while warming temperatures raise the risk of more extreme rainfall.

After several days of potential severe weather in the Central U.S., forecasters are watching Friday closely as a classic set of atmospheric ingredients comes together: a dipping jet stream, a developing low-pressure system, a dragging cold front, and warm, moist air that could help fuel strong storms.

Warmer air may be winning out across parts of the South, but winter is still influencing northern regions. Light snow and a risk of ice could complicate travel from the Ohio Valley to the Appalachians and into parts of the mid-Atlantic today, with additional snow and some ice possible later this week in the Northeast and New England.

After a brief taste of milder air, a cold front is set to bring freezing temperatures back to the D.C. region, along with periods of light snow, a wintry mix, and a short-lived risk of icy travel early Tuesday.

The start of spring depends on how you define the season. In the UK, meteorological spring runs from 1 March to 31 May, while astronomical spring begins around 20 March at the vernal equinox. Both approaches are widely used, and each helps explain different aspects of seasonal change, from climate records to the lengthening of days and the first signs of growth.

Vietnam’s national meteorological agency warns of widespread showers and thunderstorms across the South, the Central Highlands, Khanh Hoa, and eastern Lam Dong, with localized heavy rainfall and associated hazards such as lightning, strong gusts, and possible flash floods.

After a major winter storm delivered more than two feet of snow in parts of the Northeast, forecasters say the region could face additional rounds of snow and mixed precipitation through late February and into early March, though some details remain uncertain.
