As Alvin degenerates, remnants could bring unusual pre-monsoon rainfall over Desert Southwest
PHOENIX – A surge of moisture, due in part to the placement of an upper-level low and the tropical moisture field from the Northern Hemisphere's first tropical cyclone of the year, will lead to increased rain chances across the Southwest over the next several days. Moisture from the remnants of Tropical Storm Alvin will help increase humidity levels and eventually rain chances for cities such as Phoenix and Yuma, and potentially as far west as Las Vegas and Palm Springs, California. Forecast models generally expect less than 0.25 inches of rainfall across southeast California, while parts of Arizona could see totals closer to half an inch. Forecasters caution that rainfall amounts could be enhanced over higher terrain, where totals of up to an inch are possible, potentially leading to minor flooding in downstream areas. An isolated thunderstorm cannot be ruled out, but the main impact will come from the unusual rainfall for this time of year. Southwest Monsoon Season Is Here: What You Need To Know According to National Weather Service historical data, Phoenix Sky Harbor Airport has only recorded measurable rainfall 38 times during the last week of May and the first week of June. Rainfall during this period is even rarer in Yuma, which has only recorded measurable rain 11 times during the same window since the late 1800s. The FOX Forecast Center stresses that the increased humidity and rainfall are not part of the annual monsoon, which typically begins around June 15 and lasts through Sept. 30. Cities in the Southwest accumulate roughly half of their annual precipitation during the months of June, July, August and September, though amounts can vary significantly. The monsoon pattern is closely linked to the status of the El Niño-Southern Oscillation, or what is commonly called the ENSO. During La Niña events, the monsoon signal is typically more expansive and leads to heavier rainfall, while El Niño conditions can delay the start of the rainy season. How To Watch Fox Weather The unusual early-season rainfall will bring major benefits, including reduced wildfire potential and cooler temperatures. Highs during the second half of the weekend are expected to only reach the lower 90s, a significant drop from recent temperatures reaching 100-110 degrees. Any relief is expected to be temporary, as a building heat dome late next week and into the second week of June could bring the hottest temperatures of the year so article source: As Alvin degenerates, remnants could bring unusual pre-monsoon rainfall over Desert Southwest

Daily Weather Update from FOX Weather: Tropical Storm Alvin starts to weaken, heat wave bakes millions in West
Welcome to the Daily Weather Update from FOX Weather. It's Friday, May 30, 2025. Start your day with everything you need to know about today's weather. You can also get a quick briefing of national, regional and local weather whenever you like with the FOX Weather Update podcast. Tropical Storm Alvin is unraveling quickly as it churns large swells towards portions of western mainland Mexico and the Baja California Peninsula, bringing an increased risk of life-threatening rip currents. The FOX Forecast Center said land impacts are expected to be minimal as it treks over much cooler water and encounters hostile winds aloft. Alvin's winds peaked at 60 mph Friday morning after forming in the Eastern Pacific south of Mexico the day prior, after becoming the first named storm of the 2025 hurricane season. Maximum sustained winds have since decreased to near 50 mph. A Georgia community is reeling after a tornado touched down in Henry County on Thursday. The twister tore through several homes and left an 18-year-old critically injured at a hospital, according to county police. The twister touched down just before 4 p.m. local time outside the city of Locust Grove, about 40 miles southeast of Atlanta. A blistering heat wave is driving temperatures into the triple digits this week across a vast region of the western U.S., serving as a stark reminder that meteorological summer is just days away. Nearly 20 million residents are under heat alerts stretching from the Desert Southwest to the Pacific Northwest. The hottest locations are expected to see temperatures between 105 and 110 degrees. A 20-foot shark sighting in a New England pond sent ripples of panic and excitement across the popular summer tourist destination on Memorial Day. Many initially believed a massive great white shark had ventured into the calm waters of the Great Salt Pond on Block Island, Rhode Island. However, marine experts have since identified the behemoth as a much less menacing, albeit still enormous, basking shark weighing thousands of pounds.

Out-of-control Canadian wildfires sending smoke into Upper Midwest prompt air quality alerts
MINNEAPOLIS – Extreme wildfires burning in Canada and prompting evacuations are now impacting the U.s., as weather systems will cause smoke to drift southward into areas of Minnesota and Wisconsin in the Upper Midwest late this week. More than 160 wildfires across Canada have burned more than 1.6 million acres. Fast-moving fires across Saskatchewan and Manitoba triggered evacuations this week. How Is Air Quality Measured? The fires in Manitoba prompted provincial officials to issue a state of emergency. "This is the largest evacuation in many Manitobans' living memory, and this will require significant resources and co-operation from all levels of government," Manitoba Premier Wab Kinew said. "I have spoken with the prime minister, and we have asked for the support of the Canadian Armed Forces in transporting evacuees. There are hundreds of people who are mobilized to get you to safety and provide help. This is what Manitobans do, and we will get through this." The FOX Forecast Center is tracking smoke across the Upper Midwest and Great Lakes through Friday evening. Wildfire smoke will drift over cities including Duluth and Minneapolis in Minnesota and Green Bay and Milwaukee in Wisconsin. The Dakotas will also experience some smoke. By Friday night, smoke could move down into Illinois, including Chicago. Air quality alerts are in effect for parts of the Upper Midwest, including areas west of Lake Superior to the Canadian border. The air quality in the Arrowhead of Minnesota is forecast to reach red, or unhealthy, on the air quality index. According to the National Weather Service, the smoke will drift southeastward with an area of high pressure beginning Thursday morning and could linger near Lake Superior into Friday morning. On Friday, another round of heavy smoke from wildfires will likely descend into Minnesota behind a cold front. The situation this week will be less hazardous than what Canada and the northern U.S. experienced nearly two years ago during a devastating Canadian wildfire season. In June 2023, the wildfires in Canada turned the skies across the Northeast orange and reduced air quality to hazardous – the most extreme rating on the air quality index – for major cities, including New York City, Philadelphia and Washington. The dramatic scene made Manhattan look like a Martian landscape. However, this likely won't be the last wildfire smoke from Canada to reach the U.S. this year.

Daily Weather Update from FOX Weather: Tropical Depression 1-E expected to become Alvin off Mexico's coast
Welcome to the Daily Weather Update from FOX Weather. It's Thursday, May 29, 2025. Start your day with everything you need to know about today's weather. You can also get a quick briefing of national, regional and local weather whenever you like with the FOX Weather Update podcast. The first tropical depression of the season, which formed in the Eastern Pacific, is expected to strengthen into Tropical Storm Alvin on Thursday during what could be a complex year for forecasters around the basin. Tropical Depression One-E is expected to remain far enough offshore that impacts along Mexico's coast will be limited to heightened swells and increased rip currents along beaches. Powerful thunderstorms swept across a large swath of Texas on Wednesday, producing damaging winds, hail and flash flooding that triggered water rescues and left thousands without power. The Austin Fire Department reported responding to around a dozen water rescues, with most incidents involving people stranded in vehicles or trapped in areas where floodwaters rose rapidly. Earlier Wednesday, fire officials in San Antonio responded to at least eight water rescue calls as flash flooding swamped the morning commute. An early-season stretch of heat is forecast to evolve Friday, peaking over the weekend across portions of the West. The FOX Forecast Center said Extreme Heat Warnings and Heat Advisories have already been issued for parts of California, Nevada and Arizona, where temperatures will likely soar into the triple-digits. This includes more than 14 million Americans through Saturday. If Redding, California, hits above 105 degrees on Friday, it will be the earliest the city has reached that temperature in 17 years (since May 17, 2008, when it hit 106 degrees). This would also be Redding's first 100-degree day of 2025. Florida Gov. Ron DeSantis has signed several bills into law aimed at cracking down on animal cruelty, including one inspired by a dog left abandoned during Hurricane Milton in 2024. The measures, named "Trooper's Law" and "Dexter's Law," were signed during a ceremony on Wednesday at a dog rescue facility in South Florida. Trooper's Law makes it a third-degree felony to restrain and abandon a dog outside during a natural disaster or the preparedness stage of an emergency. Talk about a wedding with a twist. These two New Mexico newlyweds kicked off their married life in an unforgettable way.
