Tropical Storm Moke is expected to bring heavy rainfall and gusty winds to the Hawaiian Islands, with the Big Island expected to receive the most rain. The storm is not expected to make landfall in Hawaii, but will still cause significant disruptions.

Why it matters

The heavy rainfall and gusty winds from Tropical Storm Moke could trigger flooding, debris, downed trees, roadway issues, and power outages in the Hawaiian Islands, especially on the Big Island.

Imagine a big storm that's going to bring a lot of rain and strong winds to the Hawaiian Islands. The storm is called Tropical Storm Moke, and it's not expected to make landfall in Hawaii, but it will still cause some problems. The rain and wind could make it hard to get around, and there might be some flooding and power outages.

Analysis

Tropical Storm Moke's Projected Path

Tropical Storm Moke is expected to travel south of the Hawaiian Islands over the next several days, bringing heavy rainfall and gusty winds to the region. The storm is not expected to make landfall in Hawaii, but will still cause significant disruptions to the islands.

Rainfall Totals and Impacts

The rainfall totals from Moke are expected to be significant, with the Big Island expected to receive 5 to 10 inches of rain, and up to 15 inches in some locations. Eastern Maui will receive 3 to 6 inches on average, while the rest of the islands could see 1 to 2 inches of rain. The heavy rainfall and gusty winds from Moke could trigger flooding, debris, downed trees, roadway issues, and power outages in the Hawaiian Islands, especially on the Big Island.

El Niño Climate Pattern and Tropical Cyclone Development

The islands are paying a price from an El Niño climate pattern, via warming waters in the eastern Pacific Ocean. Warm ocean waters are the essential fuel for tropical cyclone development, which makes this El Niño phase perfect conditions for an increased hurricane season in the region. Because it reduces vertical wind shear, meaning change in direction of winds at higher levels of the atmosphere, an El Niño climate pattern allows for tropical systems that develop in the region to avoid getting 'blown over' and falling apart.

Key points

  • Tropical Storm Moke is expected to bring heavy rainfall and gusty winds to the Hawaiian Islands.
  • The storm is not expected to make landfall in Hawaii, but will still cause significant disruptions.
  • The Big Island is expected to receive the most rain, with 5 to 10 inches expected and up to 15 inches in some locations.
  • Eastern Maui will receive 3 to 6 inches on average, while the rest of the islands could see 1 to 2 inches of rain.
  • The heavy rainfall and gusty winds from Moke could trigger flooding, debris, downed trees, roadway issues, and power outages in the Hawaiian Islands, especially on the Big Island.
The Upside

If Tropical Storm Moke plays out as expected, the heavy rainfall and gusty winds could actually help to alleviate some of the drought conditions that have been affecting the Hawaiian Islands. Additionally, the storm could bring some much-needed rain to the region, which could help to replenish water sources and reduce the risk of wildfires.

The Downside

The heavy rainfall and gusty winds from Tropical Storm Moke could trigger flooding, debris, downed trees, roadway issues, and power outages in the Hawaiian Islands, especially on the Big Island. The storm could also cause significant disruptions to the islands, including road closures and power outages.
