.@NOAA experts say the record-breaking fourth global #CoralBleaching event likely ended in mid-2025 after heat stress impacted 84% of the world’s #CoralReef areas. Scientists are now studying reefs that showed signs of resilience despite the extreme heat exposure. Although this event appears to have subsided, global heat stress still persists as ocean temperatures remain unusually warm. NOAA is forecasting continued bleaching risks for this summer and fall in the Northern Hemisphere. Learn more: bit.ly/4x5yzZq #OceanMonth @NOAACoral @CoralReefWatch

Thunderstorms with large hail, severe wind gusts and potentially a couple of tornadoes are expected this afternoon and evening in parts of the northern Plains. Strong wind gusts and marginal hail will also be possible in parts of the southern and central High Plains. A few severe wind gusts may also occur from southern Georgia into northern and eastern Florida.

The plethora of thunderstorms that broke out across the United States last night into today is the focus of this #TimeLapseTuesday. @NOAA’s #GOESEast (#GOES19) 🛰️ captured this composite imagery of the storms over a seven-hour period as they brought strong winds and large hail to many parts of the country.

#MeteorSighting: Eyewitnesses in New England and @NOAA’s GOES-19 satellite reported a bright fireball on Saturday, May 30, at 2:06 p.m EDT accompanied by a loud noise. The meteor appears to have fragmented at an altitude of 40 miles over northeast MA and southeast NH. The energy released at breakup is estimated to be equivalent to about 300 tons of TNT, which accounts for the loud noise. Eyewitness accounts supplied by the American Meteor Society.

A bolide exploded high above New England in Earth's atmosphere on Saturday afternoon, creating a loud booming noise that was heard across the region. The flash of the exploding meteor was detected from the GOES-19 weather satellite's GLM instrument.

Eleven lives were saved off Florida’s coast this week after the U.S. #SARSAT system detected an emergency beacon alert from a crashed aircraft in the Atlantic. This lifesaving rescue was made possible through coordination between @NOAA satellites and partners at @USCG, @USAirForce, and the U.S. SARSAT Program. Learn more about SARSAT: bit.ly/4dIcHeT
