Tropical Storm Juliette formed in the Pacific Ocean on August 25, 2025, hundreds of miles from Mexico’s Baja California peninsula. Concurrently, Tropical Storm Fernand was active over open waters in the Atlantic Ocean. Both storms were churning in separate oceans while officials continued to manage the aftermath of Hurricane Erin, which had recently impacted the northern region. Juliette has brought a band of subtropical moisture with light to moderate rainfall moving inland through San Diego County, eastern Inland Empire, and lower deserts of Southern California. Although the main rain band has mostly passed west, gusty winds of 25 to 35 mph have caused lofted dust in the Imperial Valley, reducing visibility to under three miles in some areas. The rainfall associated with Juliette is noted as very rare for California in August.

Although not much rain is reaching the ground and the main band is passing off to the west, rain-cooled gusty winds up to 25-35 mph are generating some lofted dust in the Imperial Valley, lowering visibility to under 3 miles in spots. #cawx https://t.co/HstUw9kqoq
