Polo remnants and upper-level troughs threaten 28 million with severe flash flooding
Hurricane Polo made landfall in Mexico’s Baja California Sur on Monday night, sending moisture-rich remnants into the U.S. Southwest. These remnants are merging with an upper-level trough to create a 'hybrid storm' that threatens life-threatening flash floods across the Southwest and Plains through Wednesday. Flood watches are currently in effect for approximately 28 million people, with the highest risks concentrated in Arizona, New Mexico, Colorado, Kansas, Oklahoma, and Texas.
