The storm began in the Deer Valley area before moving southwest, hitting central Phoenix, Tolleson and Avondale, according to local outlet Arizona's Family. A severe thunderstorm warning was also issued for parts of West Valley, which expired at 10:00 p.m. 8:45 pm MST: More showers and storms are popping up across mainly the central to northern metro. The best storm thus far in the northern metro dropped one quarter inch of rain, so some accumulations up to this amount are possible with any stronger storms that develop. #azwx — NWS Phoenix (@NWSPhoenix) August 14, 2025 Around 3,300 customers were without power in central and uptown Phoenix at around 9.45 p.m., according to Arizona Public Service.

Will California weather be impacted by the tropical storm forming near Mexico?
The first tropical storm of 2025 is forecast to form in the eastern Pacific Ocean this week and it could impact California's weather this weekend. Remnant moisture from soon-to-be Tropical Storm Alvin is forecast to push toward Southern California on Sunday in the wake of a short-lived heat wave, popping thunderstorms and potentially sparking wildfires. As of Wednesday morning, the tropical storm hasn't fully formed — sustained winds hadn't yet reached the required 39 mph — but a slowing-organizing area of thunderstorms off the southern coast of Mexico is the precursor to Alvin. The National Hurricane Center predicts a nearly 100% chance of a tropical storm developing at some point Wednesday or Thursday. Alvin would be the first named tropical storm of the season in the northeastern Pacific Ocean. In an average year, that part of the ocean doesn't produce a tropical storm until June 10, but warmer-than-normal water, around 80 degrees, is providing fuel for the forming storm. Alvin won't develop into a full-fledged hurricane, and isn't even forecast to make landfall as a tropical storm, but its moisture will move northward up Baja California on Saturday. By Sunday, remnant moisture from Alvin is expected to move all the way toward Arizona and parts of Southern California. The moist, unstable air mass could aid in thunderstorms across the Sierra Nevada, Mojave Desert and Transverse Ranges on Sunday. While Alvin won't affect California the same way Hurricane Hilary did in 2023, areas that don't experience thunderstorms will probably see increased high-altitude clouds, potentially aiding in gorgeous sunrises and sunsets. A pattern change will bring temps several degrees above normal, with a slight chance of 110+ °F. Tropical moisture will also push up from the south late weekend that will increase rain chances. There's a low chance (5-10%) for some higher end rainfall (>0.50"). #azwx #cawx — NWS Phoenix (@NWSPhoenix) May 27, 2025 A mix of wet and dry lightning is possible, which could spark a few wildfires. However, vegetation still holds some moisture from winter and spring rains and should limit the potential for large fires. The Bay Area will probably avoid thunderstorms as an incoming low-pressure system Sunday should deflect the tropical moisture closer to the Sierra.
