The Minnesota Weather Authority has issued an alert for Friday, predicting persistent, all-day rain that could slow commutes due to ponding and runoff and may delay outdoor activities; localized flooding is most likely in low-lying areas of far southern Minnesota. Stay updated via the KSTP app and radar.
The National Weather Service issued a tornado watch for much of upstate New York, including Jefferson and Lewis counties, in effect until 11 p.m. Wednesday for 16 counties. A tornado watch means a tornado is possible but not imminent; forecasters say the worst part of the system may stay south of Jefferson and Lewis, but damaging conditions remain possible. Residents should know safe locations (basement or interior room), stay alert for updates, and act quickly if a tornado warning is issued.
The Vera Rubin Observatory’s ten-year Legacy Survey of Space and Time began formal operations from Cerro Pachón, Chile, using a car-sized, 3-tonne camera to image the southern sky about every 40 seconds and revisit each field roughly 800 times over the decade. The 3,200-megapixel instrument, cooled to −100 C, feeds a massive pipeline that can issue millions of change alerts per night to brokers for quick follow-up, enabling study of supernovae, moving objects, variable stars, and other transients. Rubin combines an 8.4-meter telescope with a very wide field and runs four science programs—Solar System inventory, Milky Way mapping, time-domain astronomy, and dark matter/dark energy research—while data are processed at SLAC and distributed publicly to maximize participation over ten years.
Texas’ Hill Country faces another round of catastrophic flash floods reminiscent of last year’s disaster (which killed more than 100 people), with two deaths reported this time; residents credit timely flood alerts for better prep, even as many mourn the ongoing toll in affected communities.
Forecast calls for up to five rounds of severe thunderstorms in Madison from early Wednesday through Thursday, with risks of damaging winds, large hail, tornadoes, and possible flash flooding; a 'destructive' tag could trigger sirens and alerts. Residents should monitor updates, sign up for Dane County emergency notifications, seek interior shelter during warnings, prepare a Go Kit and three days of supplies, stay hydrated in heat, and check on neighbors.
The Vera C. Rubin Observatory’s automated alert system went live and issued roughly 800,000 notices on its first night, flagging asteroids, supernovas and other transient events by comparing about 1,000 new images to a reference; alerts can be filtered by type, brightness, or frequency to manage volume, with millions per night expected as the system scales.
The Vera C. Rubin Observatory’s new alert system detected about 800,000 changes in the night sky in one night, underscoring the massive data flow of the Legacy Survey of Space and Time (LSST), which is expected to generate up to 7 million alerts per night and around 10 terabytes of data nightly as it sweeps the southern sky; these alerts will enable rapid follow-up for events like supernovae, asteroids, and interstellar objects and are publicly accessible through the ANTARES broker.
NSF–DOE Vera C. Rubin Observatory has issued its first public scientific alerts, kickstarting real-time monitoring of the night sky (800,000 alerts issued on Feb 24). The system is designed to scale to as many as seven million alerts per night once the LSST survey begins, flagging supernovae, variable stars, active galactic nuclei, and Solar System objects such as asteroids; alerts are produced within minutes and publicly accessible through a network of brokers to enable rapid, worldwide follow-up observations. Rubin's 3200-megapixel camera and automated image differencing enable this time-domain treasure trove, guiding studies of dark matter, dark energy, and other cosmic mysteries.
France's cybersecurity agency confirmed that Apple issued multiple security alerts in 2025 about sophisticated spyware campaigns targeting individuals, including journalists and officials, with no specific attribution provided. Users receiving these alerts are advised to contact CERT-FR and avoid device modifications to aid investigations.
The next Nintendo Switch 2 restock is scheduled for July 1, 2025, at Best Buy, with Walmart expected to have a restock in mid-July. The Shortcut provides early alerts and exclusive tips to help consumers secure the console amid high demand and stock shortages.
The Vera C. Rubin Observatory will generate an unprecedented 20 terabytes of data nightly, requiring advanced cloud-based data handling, multiple data centers, and AI-driven brokers to manage and analyze the vast amount of astronomical data and alerts efficiently over the next decade.
Waze is rolling out a new update with alerts for speed bumps, first responders, speed limit changes, and detailed roundabout navigation, aiming to enhance the driving experience and improve road safety for users.
Health officials in several states, including Georgia, Maryland, Texas, and Kansas, have issued alerts about the West Nile virus after detecting cases among residents, some of which have resulted in deaths. The virus, transmitted by infected mosquitoes, can cause symptoms such as fever, headaches, body aches, and in severe cases, inflammation of the brain or membranes surrounding the brain and spinal cord. There are currently no vaccines or specific treatments available, so prevention measures such as using insect repellent, wearing protective clothing, and eliminating standing water are recommended.
Japan has issued heatstroke alerts to millions of people as temperatures reach near-record highs, with some areas experiencing temperatures of nearly 40 degrees Celsius. Authorities are urging people to stay hydrated, use air conditioners, and avoid unnecessary outings.
The Tri-State Area is preparing for more severe weather and possible flooding as heavy rain and storms are expected on Sunday. With the ground already saturated from recent storms, a Flood Watch is in place for much of the area. State and local officials are urging residents to stay home if possible and exercise caution. New York City Emergency Management has issued a travel advisory, reminding people to allow for extra travel time, use public transportation, and avoid driving on flooded streets. Orange and Rockland Utilities is prepared for possible power outages and damage, with emergency response teams on standby.
