Unusually high temperatures are hitting the West Coast, leading to record-breaking warmth in San Francisco and Los Angeles, while snowstorms disrupt the Midwest.

This March, San Francisco and other parts of the U.S. are experiencing extreme heat, with temperatures soaring to nearly 90°F (32.2°C) in the Bay Area. This unusual warmth is part of a broader heatwave affecting many states. Despite the heat, residents are enjoying outdoor activities, while others across the Midwest cope with snow and storms. Experts are warning that these temperatures, especially in Las Vegas where records may be set, are not typical for March.

SAN FRANCISCO (AP) — This March, residents of San Francisco and the Bay Area are shedding layers and soaking up unexpected high temperatures, experiencing their warmest March in two decades. With temperatures nearing 90°F (32.2°C), locals are enjoying the early summer feel.

While the Bay Area heats up, cities like Phoenix are bracing for an incredible week ahead, forecasted to hit over 100°F (37.7°C), a record for this time of year. Las Vegas isn't far behind, potentially gearing up for its earliest triple-digit temperature event on record.

In contrast, the Midwest and eastern regions are grappling with the aftermath of snowstorms, which led to widespread travel disruptions. As temperatures rise in California, many people, including sunbathers and dog walkers, flock to parks like Crissy Field for some outdoor fun.

“It feels like summer already in March! The dogs are having a blast here,” remarked a local dog walker. Others, with no air conditioning at home, are making the most of the pleasant weather while keeping cool with fans and open windows.

Record-breaking highs of 83°F (28.3°C) were recorded at San Francisco International Airport, alongside even warmer temperatures in Silicon Valley. Meteorologists are advising visitors to Las Vegas to stay hydrated as temperatures reach record levels this upcoming weekend.

As Arizona prepares for the high heat, park officials warn hikers to avoid strenuous activities during the peak sun hours. Meanwhile, Colorado is dealing with low snow levels and water restrictions due to the warm winter, reminding everyone to conserve resources as the summer approaches.
