Kelvin wave (A Kelvin wave is a wave in the ocean or atmosphere that balances the Earth's Coriolis force against a topographic boundary such as a coastline, or a waveguide such as the equator. In a nutshell, more active means more surf. The MJO (Madden-Julian Oscillation) is an eastward moving disturbance of clouds, rainfall, winds, and pressure that traverses the planet in the tropics and returns to its initial starting point in 30 to 60 days, on average, unlike ENSO which is stationary.
“Neutral” is in the middle of the continuum. The two opposite phases, “El Niño” and “La Niña,” require certain changes in both the ocean and the atmosphere because ENSO is a coupled climate phenomenon. Please visit the Central Pacific Hurricane Center website at for the most recent bulletins.ĮNSO is a single climate phenomenon, it has three states or phases.

In coordination with civil defense agencies & water safety organizations in Hawai`i, the NWS uses the criteria below for the issuance of High Surf Advisories & Warnings in coordination with civil defense agencies & water safety organizations in Hawai`i.Īll surf height observations & forecasts are for the full face surf height, from the trough to the crest of the wave. NWS criteria for High Surf Advisories & Warnings. A “typhoon” and a “hurricane” are the same kind of storm, they just go by different names…it’s only a matter of geography. Once a tropical storm begins producing sustained winds of around 75 mph, we call the storm a typhoon in the western Pacific near Asia and a hurricane in the oceans on either side of North America. A storm that reaches tropical storm strength usually gets its own name to help us quickly identify it in forecasts and warnings. Once a tropical cyclone strengthens to the point where it has gale-force winds-39 mph or greater-it becomes a tropical storm. Tropical cyclones go by many names around the world, and the terminology can get confusing. (The highest classification in the scale, Category 5, is reserved for storms with winds exceeding 156 mph).
A tropical storm is then upgraded into Category 1 hurricane status as maximum sustained winds increase to between 74 mph and 95 mph.

An upgrade to a tropical storm occurs when cyclonic circulation becomes more organized and maximum sustained winds gust between 39 mph and 73 mph. An average season has 4 to 5 tropical cyclones, which include tropical depressions, tropical storms, and hurricanes.Ī tropical depression forms when a low-pressure area is accompanied by thunderstorms that produce a circular wind flow with maximum sustained winds below 39 mph. All pleasure craft were directed to seek sheltered waters.Get the latest on the tropics at The Central Pacific Hurricane Center outlook for the 2017 Central Pacific Hurricane Season calls for 5 to 8 tropical cyclones to either develop or cross into the Central Pacific with a 40% chance for an above-normal season, a 40% chance for a normal season, and a 20% chance for a below-normal season. Coast Guard set port condition "zulu," or a danger condition, for the Hawaii County port and a "yankee" or warning condition, for Oahu, Maui, Lanai, Molokai and Kauai ports in advance of the hurricane.

Windows are boarded up in preparation for Hurricane Lane in Kailua-Kona, Hawaii, on Wednesday. He added that space is expected to be limited and people going there are expected to bring their own supplies. "They are, however, a safer option than remaining in areas prone to flooding, or exposed ridge lines or in older homes with wood frames or single-wall construction," he said. Hiro Toiya, deputy director of the Department of Emergency Management for the city and county of Honolulu, said at a news conference Wednesday most of the shelters that will be opened on Oahu Thursday morning have not been designed or reinforced to withstand winds greater than a tropical storm. Meanwhile, Oahu Emergency Management officials, who've been reviewing shelter sites across the island this week, concluded that some couldn't withstand even a category 1 hurricane, NBC affiliate KHNL of Honolulu reported. #HurricaneLane is 200 miles away from #Hawaii but outermost rain bands already causing flooding.
