Tropical Storm Rosa will bring the threat of heavy rain, which could produce flooding over the next several days. The storm is located about 90 miles southwest Punta Eugenia, Mexico in Baja California. Tropical Storm Warnings continue for most of the west coast of Baja California, with Tropical Storm Watches for the eastern coastline. The storm will continue to weaken as it moves into Mexico and Arizona, but the threat for flooding rains will continue. High surf is likely along the southern California coast.
Flash Flood Watches extend from Idaho to Arizona with the potential for up to 4″ of rain. These rains are expected to produce life-threatening flash flooding and debris flows in the deserts, with mudslides and landslides in mountainous terrain. In addition, larger streams and rivers could experience significant rises and possible flooding due to the widespread heavy rainfall.
