Hundreds of thousands of people in Hawaii are facing dangerous swimming conditions on Tuesday as large waves pummel the shores of popular beaches.
Why It Matters
Hawaii's south-facing beaches saw powerful waves and hazardous ocean conditions this week, prompting warnings for hundreds of thousands of residents and tourists. The National Weather Service (NWS) issued a high surf advisory due to a significant south swell, urging the public to heed safety precautions.
This advisory followed a series of extraordinary weather and seismic events across the Pacific, including recent tsunami warnings stemming from a massive earthquake in Russia. While the NWS emphasized the current surf warning was separate from those events, officials underscored the ongoing risk to swimmers, boaters and anyone near the shoreline.
What To Know
The NWS Honolulu office issued a high surf advisory for all south-facing shores of the Hawaiian Islands, reporting that surf heights could reach from 7 to 10 feet. According to the NWS advisory released at 3:25 a.m. HST on Tuesday, surf conditions were expected to remain hazardous until at least 6 p.m. HST that evening.

The affected areas included all major islands, with specific warnings for regions such as Niihau, Kauai Southwest, Waianae Coast, Maui Leeward West and the Big Island South, among others.
The advisory attributed the high surf to a moderate-size, long-period south swell that peaked Monday night, with another swell forecast to arrive later in the week.
The NWS alert cautioned that strong breaking waves and strong currents would make swimming dangerous throughout the advisory period. Residents and visitors were urged to follow the advice of ocean safety officials and to avoid entering the water if uncertain about conditions.
A similar advisory was issued last week, with waves reaching up to 14 feet. Those waves were caused by a long-period south swell that originated south of New Zealand. At the time, NWS meteorologist Laura Farris told Newsweek the high surf is a typical summer pattern.
Summer is peak high surf season for Hawaii's south-facing shores. The average surf for this time of year is around 6 feet.
What People Are Saying
NWS meteorologist Derek Wroe told Newsweek: "It's coming from a distant swell from east of New Zealand. That's our typical source area for surf in the summertime, so it travels quite a long time to get here."
NWS Honolulu in a high surf advisory: "Strong breaking waves and strong currents will make swimming dangerous. Heed all advice from ocean safety officials. When in doubt, don't go out."
What Happens Next
The high surf advisory for Hawaii's south-facing shores remained in effect until 6 p.m. HST Tuesday, but NWS officials will monitor the conditions closely, as another south swell was forecast to arrive late Wednesday or early Thursday. This new swell could bring advisory-level waves back to the region.
Residents and visitors were urged to remain vigilant, stay updated through official NWS notifications and prioritize safety, as conditions could change.

Earthquake Hits Alaska: What to Know
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. An area near Petersville, Alaska, was hit with a 4.6 earthquake on Wednesday, according to the United States Geological Survey. Newsweek reached out to the USGS's Earthquake Hazards Program via email for additional comment. Why It Matters Communities along the Pacific, including Alaska and the U.S. West Coast, faced recent warnings after a powerful 8.8 magnitude earthquake struck off Russia's Kamchatka Peninsula last week. The rapid alert responses and evacuation orders demonstrated the possible vulnerability of coastal areas to seismic and tsunami activity, underscoring the continued significance of preparedness for American residents in earthquake-prone zones. This event also revived concerns stemming from previous devastating tsunamis in recent memory. What To Know Wednesday's earthquake hit 23 kilometers WSW of Petersville, the USGS said, around 1:38 p.m. local time. The quake was 84.4 km deep. The coordinates of the earthquake are 62.447°N 151.216°W. The earthquake that took place last week in Russia had an impact felt across the Pacific.

Torrential rainfall that hit Chicago on July 25 only happens once every 1,000 years
The torrential rainfall that pounded parts of Chicago on July 25 was so extreme, it typically occurs only once every 1,000 years, according to the National Weather Service. Midday July 25, a corridor of extreme rainfall developed along a stalled atmospheric boundary on the south side of Chicago. As much as 5.61 inches of rain fell in Garfield Ridge in just two hours. Extreme rain was also observed in Bedford Park near the border with Clearing, where an unofficial gauge measured 5.98 inches in three hours. Such extreme rainfall rates only have a 0.1% chance of occurring in a given year, according to the NWS. This would have once been referred to as a 1-in-1,000 year rainfall event, but the NWS now avoids that phrasing since there is no guarantee it will be another 1,000 years before it happens again. Other communities from far eastern DuPage County eastward through central Cook County recorded 3 to 5 inches of rain in three hours, including Darien, Burr Ridge, Bridgeview, West Lawn and West Englewood. Rainfall of this magnitude is only statistically expected in these areas once every 100 years. This extremely rare rain event comes on the heels of the July 8 storm that dumped 5 inches of rain in less than three hours on a different part of central Chicago -- an event only expected once every 500 years, according to the NWS. "As of July 25, 2025, the 2020s decade has had five extreme rainfall events in central Cook County," National Weather Service Senior Service Staff Hydrologist Scott Lincoln said. This is a marked increase compared to two extreme rainfall events in both the 2010s and 2000s, and one extreme rainfall event in each the 1990s, 1980s, 1970s and 1960s. As global climate change warms Chicago area temperatures, it is leading to heavier rainfall events. For every one degree of warming, the atmosphere holds 4% more moisture. "Multiple lines of evidence suggest that the threshold for 'extreme rainfall' in the Chicago area is changing," Lincoln said. "Analysis of daily rainfall in Chicago indicated that 'extreme' 1-day rainfall early in Chicago's history (1871-1930) was approximately 6 inches, while this value increased to just over 8 inches in more recent times (1961-2020)."

Expert Addresses Model Showing Major Hurricane Hitting Florida This Month
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. A recent run of the Global Forecast Model (GFS) showed the possibility of a major hurricane hitting Florida's east coast this month, prompting weather hobbyists to share their concerns across social media. However, AccuWeather Lead Hurricane Expert Alex DaSilva told Newsweek that the model doesn't necessarily indicate a true outcome and that Floridians shouldn't worry based on the predictions of one forecasting model. Why It Matters The widespread social media posts sharing the model comes as the National Hurricane Center (NHC) tracks three systems in the Atlantic Ocean: Tropical Storm Dexter, which is currently moving further out to sea, and two disturbances, one in the central tropical Atlantic and one brewing much closer to the U.S. Each disturbance has a moderate chance at strengthening into a tropical storm in the coming days. A hurricane is seen from space. A hurricane is seen from space. buradaki/Getty What To Know Of the two systems that could strengthen into Tropical Storm Erin, the fifth named system of the season, the one closer to the U.S. originally appeared as though it would move inland, but DaSilva said the system now looks as though it will run parallel to the coast. The other system, in the central tropical Atlantic, has a higher chance of developing, though DaSilva said meteorologists are anticipating it will take a turn out to sea east of Bermuda. And although the storm could "very well" strengthen into a hurricane, DaSilva urged people to be cautious when assessing a single GFS model, specifically one with a long-term forecast. "Essentially, it's one run of one model," DaSilva told Newsweek. When meteorologists assess a forecast, specifically one that is a further way out, they assess forecasting model ensembles rather than only one model. The ensembles can give a "better idea than looking at one model one time," DaSilva said. "If we saw a lot of ensembles taking a major hurricane into Florida, and we saw the European model doing the same thing, we would be much more concerned," he said. DaSilva added that the GFS, which can provide forecasts more than two weeks in advance, has a bias in which it exaggerates a storm's impact in its longer-range forecasts. "This is a known thing. Meteorologists look at that and take it with a grain of salt, and the general public may say, 'oh no, here comes a major hurricane,'" DaSilva said. DaSilva urged people, especially those in hurricane-prone areas, to take advice from a meteorologist and not a "random person on social media posting one model." What People Are Saying AccuWeather Lead Hurricane Expert Alex DaSilva told Newsweek: "When you see people posting the doomsday scenario on social media from one run, that is just one run. There are many other runs, many other models have to be looked at." The National Hurricane Center, in an updated outlook for a disturbance near the Southeast coast: "A weak area of low pressure has formed from a surface trough, several hundred miles off the coast of the southeastern United States. However, this system is currently producing only limited shower and thunderstorm activity and development is likely to be slow to occur during the next few days. Thereafter, environmental conditions could become a little more conducive for development. A tropical depression could still form by this weekend as the low initially drifts westward before turning northward to northeastward by the weekend." What Happens Next Even if the two disturbances monitored by the NHC don't develop into tropical storms, some weather hazards could still impact the East Coast later this week, including torrential rain and dangerous rip currents. People along the East Coast are urged to follow local weather guidance as meteorologists continue tracking the systems.
