Roman blazed toward an observation point 1 million miles away that's home to the Webb Space Telescope, one of NASA's other big-ticket eyes in the sky. “Roman is exactly the kind of success story we want to see across NASA,” said NASA Administrator Jared Isaacman. “Delivered ahead of schedule and on budget, this mission reflects more than a decade of dedication from the NASA workforce and our industry partners.

Dolly lasted for about 24 hours in the Atlantic as a Tropical Storm. Remnants of Dolly are targeting the Caribbean Just about 24 hours as a tropical storm, Dolly dissipated in the Atlantic Ocean on Friday after struggling to develop as it battled the hostile conditions produced by the inhibiting El Niño climate pattern. THE TAKEAWAYAfter just 24 hours, Dolly dissipated from a tropical storm in the Atlantic. The NHC has issued a 10% chance of development for Dolly's remnants. Dolly's remnants are bringing heavy rain to the Caribbean islands. Just about 24 hours as a tropical storm, Dolly dissipated in the Atlantic Ocean on Friday after struggling to develop as it battled the hostile conditions produced by the inhibiting El Niño climate pattern. In the last advisory, the National Hurricane Center issued a 10% chance of development for Dolly's remnants over the next seven days.

A dip in the jet stream left behind a cluster of thunderstorms which has turned into a small tropical disturbance in the northern Gulf. Officially, it’s tagged Invest 97L by the National Hurricane Center. The system is trapped under the heat dome high-pressure system that's bringing hot weather to the Midwest, which will slowly nudge it toward the upper Texas coast. WHAT IS A HEAT DOME AND HOW CAN IT AFFECT YOU DURING THE SUMMER MONTHS? The National Hurricane Center puts the odds it will reach tropical depression status in the low range. It only has a couple of days, but the Gulf water is plenty warm, and the atmospheric pattern looks reasonably conducive to development. Tropical activity in the Atlantic basin over the next week. (Bryan Norcross)There's a long history of small systems spinning up quickly in the northwestern Gulf, of course. The curvature of the coast and the extremely warm water contribute to that phenomenon. Everyone from Galveston to Southwest Louisiana should stay in touch with the forecast over the next couple of days just in case something unexpected happens.

See the moment a mudslide engulfs buildings at Nepal-China borderRising water levels in the Bhotekoshi River prompted Nepalese authorities to warn of potential new flooding on Sunday, urging residents in vulnerable, devastated districts to stay on high alert.

THE TAKEAWAYGlacial lake outburst floods (GLOFs) can send destructive waters and debris racing downstream with little warning. Alaska’s Suicide Basin produces near-annual GLOFs, but close monitoring helps protect Juneau. Remote Himalayan communities face greater danger when high-mountain lakes are not monitored. JUNEAU, Alaska – With little warning, water trapped behind a glacier or natural dam can suddenly break free, unleashing torrents of water, ice and debris that have caused some of the world’s most devastating and unexpected natural disasters. Known as a glacial lake outburst flood, or GLOF, the phenomenon occurs when water trapped behind a glacier or loose moraine dam suddenly breaks free, sending a powerful surge racing downstream. WHAT IS A GLACIAL COLLAPSE? HOW COLLAPSING ICE CAN TRIGGER DEADLY FLOODS, LANDSLIDES AND TSUNAMIS Tsho Rolpa Lake, a moraine-dammed glacial lake in Nepal’s Himalayas. The expanding lake remains closely monitored because a dam failure could trigger a destructive glacial lake outburst flood downstream. (ICIMOD)The U. S.

A historic El Niño may be right around the corner as we get closer to fall, with signs that it’s already here in some capacity. While strong El Niño events typically result in warmer winters across Canada, their influence on fall weather is different. The Pacific Ocean has been warming up along the equator, while the chance for the historic climate pattern to stick is building. Experts believe that a very strong El Niño will be present going into the fall and winter months, estimated at a 90 per cent likelihood. El Niño's impact on fall may be different than you expectSince 1950, we’ve seen seven separate years with a strong El Niño during the fall, or from September to November, with the last strong pattern from 2023. DON'T MISS: Latest El Niño forecast calls for historic heat by this autumnWarmer winter months are associated with a strong El Niño in Canada, but the effect is different in the fall months, depending on where you are in the country. A pronounced trough normally settles over Ontario, while a more dominant ridge covers the upper West Coast during these autumn months.

A stormy Saturday spawned very large hail and rotation across parts of the Prairies. We’ll see a renewed threat for severe storms develop throughout Sunday, with multiple rounds of hazardous weather expected. Be sure to monitor the radar if you’ve got plans through Sunday night, and stay aware of potential watches and warnings in your area. DON’T MISS: What is a mesoscale convective system? How an 'MCS' can spell dangerMoisture and instability streaming over the Prairies to end the weekend will bring a fresh threat for strong to severe thunderstorms across the region. The greatest concern will exist in southern Saskatchewan into southern Manitoba, including areas around Regina and Brandon. Sunday will start with morning thunderstorms across central Saskatchewan. These cells should remain non-severe, but downpours and small hail are possible. Content continues belowStorms will organize and tap into higher instability over eastern Saskatchewan by Sunday afternoon, quickly developing into one or more lines as a low-pressure system develops near the international border. This activity will increase the potential for damaging winds and large hail in southeastern Saskatchewan.

A typhoon set to make landfall in China will have impacts all the way in British Columbia. Typhoon Saudel has already pounded Japan's southwestern islands, dumping 230 mm of rain in 24 hours and cancelling over 150 flights at Okinawa Naha Airport. The storm made landfall in mainland China early Friday morning local time. TROPICAL STORMS: The Weather Network’s Hurricane and Tropical Storm HubSaudel’s moisture heads eastAlthough Saudel will weaken over China, its moisture will spread eastward across the Pacific. A low-pressure system over the Bering Sea will pull moisture into Alaska, while high pressure off the B. C. coast directs an atmospheric river toward the North Coast. The North Coast mountains could receive 50 to 75 mm of rain through Saturday, providing welcome relief after a drier-than-normal previous 30 days.

Unbelievably, this state approaches record for most tornadoes in a yearIllinois has already smashed its record for tornadoes in any year, and it's approaching an all-time U. S. record for any state, amid an active 2026 of severe weather in the Midwest.210, so farAs of Aug. 29, 210 tornadoes have been confirmed in Illinois so far this year, according to the National Weather Service in Romeoville, Illinois. This tally includes several tornadoes from the Aug. 11 derecho, one of which hit the southside suburbs of Chicago. That's by far the most the state has documented in any year in reliable records dating to the 1950s, crushing the previous record of 142 Illinois twisters from 2024. It's also more than three times their yearly average of 66 tornadoes, according to NOAA's Storm Prediction Center.

Burning Man's mud problem is a 15,000-year-old issueBurning Man has seen major impacts from rain and storms during the festival's previous years, which turns the venue into a muddy mess. But the flooding at the Black Rock Desert in Nevada isn't due to the amount of rain that falls; it happens because of the soil on which it falls on. What is going on with the soil here? The Black Rock Desert's origin story dates back 15,000 years. The Desert lies in the lake bed of the ancient Lake Lahontan. This lake deposited sediment that formed an extremely flat surface. Just how flat? In an area of about 119 square miles in the lake bed, the elevation changes by about 3 feet.

The area is flat, but you also have the sediment itself. This sediment-covered soil struggles when water is present. It expands when wet, turning the ground into a very sticky mud that is difficult to traverse.

Thunderstorms are expected to form across the Prairies on Sunday, extending from southern Saskatchewan to southern Manitoba. An upper-level low over southern B. C. will move toward the Prairies, pulling moisture north and causing atmospheric instability. That setup could help fuel a series of showers and thunderstorms throughout the day. The greatest concern is in southern Saskatchewan and Manitoba, including areas near Regina and Brandon. Storms may bring strong winds, heavy rainfall and large hail.

THE TAKEAWAYTropical storms Karina and Lowell are likely to become hurricanes. Two other areas to watch carry medium and high chances of development, respectively. Warm waters of the Central and Eastern Pacific are very favorable for tropical development amid strengthening El Niño. The flurry of tropical activity in the Pacific continues as tropical storms Karina and Lowell and two other disturbances cause a tropical ‘traffic jam,' fueled by a strengthening El Niño. Current tropical activity across the Pacific Basin, along with designated development percentages(FOX Weather) Tropical Storm Karina is moving northwest at 12 mph with 70 mph wind gusts, according to the National Hurricane Center. According to the National Hurricane Center (NHC), Karina is likely to become a hurricane on Saturday. REMNANTS OF DOLLY SHOWING POTENTIAL FOR REDEVELOPMENT, AS NEW AREA TO WATCH IS DESIGNATED IN THE GULFKarina is forecast to become a Category 3 or stronger hurricane by next week. This graphic shows what you need to know about Tropical Storm Karina.(FOX Weather) The agency also said Tropical Storm Lowell is moving west at 8 mph with 45 mph wind gusts.

THE TAKEAWAY Ridge-riding storms are taking hold of the North this weekend. They're bringing rain to the Upper Midwest and Great Lakes, where some places have seen their wettest year on record. Rain and storms move into the Northeast Monday and hang on through Wednesday. After a few quiet weather days in the Upper Midwest and Great Lakes, a soggy weather pattern is returning through ridge-riding storms, bringing a renewed flash flood threat to the region. As a ridge of high pressure remains across the South, energy and storms will continue riding along its edge from the Northern Plains into the Upper Midwest, Great Lakes and Northeast through early next week. Ridge-riding storms set up(FOX Weather) With plenty of moisture, southerly winds at the ground will be pulling humid air north, allowing storms capable of intense rainfall rates and localized flash flooding every day through Monday. On Sunday and Monday, an area of low pressure coming from the Rockies will increase moisture and instability as it moves into southern Canada. WHAT IS A RIDGE RIDER AND HOW DO THEY FORM?

Dolly is no longer a tropical storm, but the remnant disturbance still carries very gusty winds and pockets of heavy rain. The squally moisture surge will move over Antigua and the surrounding northeastern Caribbean islands today and Puerto Rico and the nearby islands beginning tomorrow. Dolly's moisture will linger until at least Tuesday. On the mountainous islands, heavy rain is possible, which could cause local flooding. Winds could gust to 40 mph or higher in squalls. Stay aware of any alerts issued by the National Weather Service in San Juan. Remnants of Dolly in Atlantic basin (Bryan Norcross)Last updated at 9:00 a.m. on Saturday, Aug. 29, 2026. There continues to be a slight chance that the leftover disturbance from Dolly will regenerate later this week as it heads in the general direction of Florida. There's no clear signal in the models about where that might happen. There's a high probability that Dolly's remnants will die out over the tall mountains of Puerto Rico and the Dominican Republic, and that will be that. Just in case, the National Hurricane Center is drawing a very low odds potential development area north of the Caribbean islands.

THE TAKEAWAYAug. 29, 2026 marks the 21st anniversary of Hurricane Katrina's landfall in Louisiana. Adjusted for inflation, NOAA estimates the 2024 value of damage caused by the storm to be north of $201 billion. Within 48 hours of landfall, authorities estimated that 80% of New Orleans was underwater. NEW ORLEANS – Twenty-one years ago, Hurricane Katrina roared ashore along the Gulf Coast, leaving an indelible mark as one of the deadliest and most destructive disasters in U. S. history. The cyclone first developed on Aug. 23, 2005, as a tropical depression over the southeastern Bahamas and, within a day, strengthened into Tropical Storm Katrina before moving toward Florida.  next Flood waters from Hurricane Katrina cover streets on August 30, 2005, in New Orleans, Louisiana.
