Schools and ports remain closed, and swimming is prohibited on Mexico's beaches. Hurricane Polo has once again reached the highest category, Category 5. Although it remains offshore, heavy rain continues to pose a threat of flooding and landslides.

Polo's rapid development is extraordinary: In just about 40 hours, it intensified from a tropical depression into a Category 5 hurricane. Further west, Hurricane Odalys is also churning in the Pacific, but is currently having no impact on land.

Hawaii is also facing the threat of a hurricane: Another tropical storm named Nolo could intensify significantly by Friday and pass south of the Big Island. This season has been exceptionally busy for Hawaii, with two storms causing direct and significant impacts to the chain of islands: Lala and Lowell. Nolo will likely be the third one this season.
