Three Pacific hurricanes, led by Category 4 Polo, threaten heavy rain and flash floods in the Southwest as a strong Nor’easter hits the East Coast.
Hurricane Polo was packing maximum sustained winds of 155 miles per hour as of 8 a.m. ET Saturday and moving west-northwest at about nine miles per hour, Newsweek reported. Two other Pacific systems, Odalys and Nolo, were also active, each with sustained winds near 105 miles per hour.
The National Hurricane Center is warning that moisture from the storms could feed “a heavy rainfall and flash flood threat” across parts of the southwestern United States this weekend and into next week. A separate system is expected to strengthen into a strong Nor’easter along the East Coast over the same stretch of days.
Residents from the Desert Southwest to Hawaii to the Mid-Atlantic now face overlapping forecast hazards: flash flooding, dangerous surf, mudslides, coastal flooding, and power-outage risk from high winds.
Polo is forecast to make landfall in Baja California Sur, Mexico, early next week. The National Hurricane Center has flagged the chance of life-threatening flooding and mudslides beginning Sunday, along with dangerous surf and rip currents along portions of the northwest coast of Mexico and Baja California for the next few days.
Odalys was moving north at seven miles per hour. Southern swells from that storm are expected to reach the southwestern United States through the middle of next week and likely overlap with Polo’s moisture.
That combination matters most for inland states. The National Weather Service’s Phoenix office posted a model projection showing how a weather system could interact with deep moisture from Polo and Odalys.
NWS Phoenix stated:
“Here is a model projection of how a weather system will interact with deep moisture from Hurricanes (Polo and Odalys) to potentially bring widespread heavy rain to much of the Desert Southwest early next week. This will lead to a heightened risk for flash flooding.”
Areas under the rising rainfall threat include Arizona, New Mexico, northern Texas, Oklahoma, Colorado, and Kansas. Desert washes and normally dry ground can turn dangerous fast when tropical moisture arrives in bulk.
Farther west, the National Hurricane Center upgraded Nolo to a hurricane Thursday night. The storm was located south of Hawaii with sustained winds of 105 miles per hour.
Forecasters called for periods of heavy rain and the potential for significant, life-threatening flooding and mudslides, especially on the Big Island and eastern Maui. Hurricane conditions were possible later in the day in steep terrain, with powerful gusty winds expected across the Hawaiian Islands as the weekend progressed.
Tropical systems do not need a direct hit to cause serious trouble in Hawaii. Heavy rain on steep slopes is enough.
While the Pacific stayed busy, the National Weather Service’s Weather Prediction Center forecast a strong Nor’easter to rapidly intensify off the Mid-Atlantic Coast on Saturday. The system was then expected to head toward the New Jersey coast late Saturday and Sunday.
Forecast hazards include major coastal flooding along the Mid-Atlantic Coast over multiple high tide cycles through the weekend, plus gale-force winds across much of the U.S. East Coast. Gusts of 45 to 65 miles per hour could bring power outages for Eastern Long Island and southwestern New England.
Other areas in the broader threat zone include Southern New England, the Carolinas, and stretches of the wider East Coast shoreline. Coastal flooding stacked across successive high tides is often what catches communities off guard.
Newsweek noted the Pacific has recorded an unusual number of hurricanes this year because of the El Niño climate pattern, which warms equatorial Pacific waters and creates more favorable conditions for storm development.
That backdrop helps explain why three named hurricanes were moving at once, and why U.S. forecasters are tracking moisture plumes, surf, and flood risk well beyond the immediate landfall zones in Mexico and the open Pacific.
No injuries, deaths, or confirmed damage were reported in the available forecast updates. The warnings remain forward-looking: heavy rain, flash flooding, mudslides, rough surf, coastal flooding, and wind-driven outages.
Official maps and key messages from the National Hurricane Center, the Weather Prediction Center, and NWS Phoenix are the practical guides for timing and local risk. Conditions can shift as the systems move.
When three Pacific hurricanes and an East Coast Nor’easter line up on the same weekend, the people who pay the price first are the ones living in floodplains, coastal towns, and desert valleys, not the officials issuing the maps. Preparation still beats surprise.
