Two powerful tropical systems commanded attention on opposite sides of the Pacific Ocean over the weekend, with one taking aim at Mexico's Baja California peninsula and the other gradually loosening its grip on Hawaii.
Hurricane Polo, a major Category 3 storm, was tracking northward toward the southern tip of Baja California on Sunday evening, prompting residents and authorities across the region to prepare for what forecasters warned could be a dangerous landfall early in the week. At the same time, Hurricane Nolo continued to drift away from the Hawaiian Islands, though its lingering effects remained a concern for parts of the Big Island.
According to the U.S. National Hurricane Center in Miami, Polo carried maximum sustained winds of about 125 mph (205 kph) as of Sunday evening. The storm was positioned roughly 270 miles (435 kilometers) west of Cabo San Lucas, the resort city at the peninsula's southern extremity, and was advancing to the north at approximately 12 mph (19 kph).
Forecasters expected Polo to make landfall along the Baja California peninsula on Monday, bringing with it a combination of storm surge, high winds and torrential rainfall. Heavy rain was projected to begin affecting the peninsula overnight Sunday, raising the risk of life-threatening flooding and mudslides in the region's rugged terrain.
The hurricane center also cautioned that Polo would likely continue on a path that would carry it across Baja California and then over the Mexican mainland. Beyond that, moisture associated with the storm could contribute to heavy rainfall and flooding in portions of the southwestern United States later in the week, extending the system's reach well beyond its initial landfall zone.
Baja California is no stranger to tropical cyclones, but major hurricanes making direct hits on the peninsula remain relatively uncommon because of the region's geography and the typical track of storms forming off Mexico's Pacific coast. When such systems do approach, the combination of steep desert terrain and isolated communities can complicate evacuation and rescue efforts, and flash flooding often poses a greater danger than wind alone.
While Mexico prepared for Polo, the situation in Hawaii showed signs of easing. Hurricane Nolo was positioned well southwest of the islands and was moving away from the Big Island as the weekend came to a close, according to forecasters.
Even so, the storm's maximum sustained winds had increased to near 105 mph (165 kph), making it a formidable system despite its distance. A high-wind warning, a wind advisory and a high surf advisory remained in effect for portions of the Big Island through Sunday evening, a reminder that hazards can persist even as a hurricane recedes.
The storm's effects were visible on the ground over the weekend. Fire Captain Lui Sales of the Hawaii Fire Department was photographed searching for residents who might need assistance as rainwater from nearby Hurricane Nolo flooded a section of the Mamalahoa highway on Saturday, Sept. 26, near Naalehu, Hawaii. The image underscored the flooding threat that forecasters had been emphasizing as the storm churned through the region.
Earlier in the week, Nolo had drawn intense scrutiny as it approached the islands. The storm was notable for its erratic, zig-zagging path, which complicated forecasting efforts and kept residents on edge. Forecasters had warned that Nolo was likely to bring dangerous flooding rains even if it avoided a direct landfall, and the weekend flooding in parts of the Big Island appeared to bear out those concerns.
The juxtaposition of the two storms illustrated the breadth of the Pacific hurricane season's activity. Polo and Nolo formed and intensified in different parts of the ocean basin, each posing distinct challenges: Polo as a landfalling major hurricane threatening Mexico and potentially the U.S. Southwest, and Nolo as a slow-moving system whose heavy rains and high surf menaced Hawaii's communities.
Authorities in Baja California were expected to continue monitoring Polo's progress closely as it neared the coast. Residents in low-lying areas and flood-prone communities were advised to take precautions, while emergency management officials prepared for the possibility of evacuations and rescue operations depending on the storm's exact track and intensity at landfall.
The eventual impact on the southwestern United States remained uncertain and dependent on how much of Polo's structure survived its passage over Baja California and the Gulf of California. Forecasters noted that remnant moisture from Pacific storms can sometimes travel far inland, producing heavy rain in arid regions where the ground absorbs water slowly and flash flooding can develop quickly.
For Hawaii, the coming days were expected to bring a gradual return to calmer conditions as Nolo continued its westward retreat. However, officials urged residents to remain cautious about residual hazards, including elevated surf, strong currents and saturated ground that could still give way in areas that received heavy rainfall over the weekend.
Taken together, the two storms served as a reminder of the destructive potential of hurricanes at their peak and the importance of timely warnings, preparation and public awareness in minimizing the risks to life and property.
