Tropical Storm Darby continues to maintain its strength as it barrels down towards Hawaii. Maximum sustained winds are remaining at 60 mph with higher gusts. Latest satellite imagery shows convection mainly confined to the western side of the storm with the center of circulation nearly exposed. The current track of Darby keeps the storm on a westward track through the early morning hours on Saturday before beginning a slight WNW jog towards the Big Island of Hawaii. As the storm approaches, the threat for heavy rain and gusty winds will increase with conditions slowly deteriorating after daybreak along the southern and easternmost coastline of the Big Island.
Expect surf to become increasingly rough along with a threat for dangerous rip currents during the day on Saturday along the beaches of the Big Island of Hawaii. As the storm continues its WNW to eventually NW direction, the storm should continue to weaken. However, the impacts of the storm will still be felt along the Hawaiian Islands of Molokai, Maui and Oahu through late this weekend and into early the upcoming week. Expect less in the way of dangerous flooding and high winds as the storm slowly weakens. Although, areas of heavy rain will still bring the potential for isolated flooding in spots. Along the coastlines, heavy surf and riptides will also become a possibility as breezy winds and rain showers continue.
By mid week, Darby should become post-tropical and drift far north of the island and should not pose any additional threats to any land masses.
Elsewhere, Tropical Storm Frank continues to grow in size and intensity about 360 miles west of Manzanillio, Mexico. Expect Frank to grow into a hurricane as early as late Sunday night as the storm continues its northwestern track away from any landmasses. The effects of Frank will be limited to mostly the far southwestern coastline of the Baja of California with increased surf and the potential of riptides. Fortunately, Frank will quickly weaken as the storm heads out to sea by the middle to later part of next week.
Along with Frank, Tropical storm Georgette has also formed 940 miles southwest of the southern tip of Baja California. Georgette will likely slowly intensity and may become a hurricane by late Saturday night. Expect no impacts to any landmasses as the storm stays out to sea and should fully dissipate by the middle part of next week.
Elsewhere, no tropical disturbances exist or are forecast to develop within the next few days.
