Hurricane Iona 'rapidly weakening' in the Pacific Ocean: See tracker
Hurricane Iona is "rapidly weakening" well to the south of Hawaii, and more weakening is expected on Wednesday, the National Hurricane Center said in an advisory late Tuesday night. In an advisory issued at 11 p.m. local time on Tuesday, July 29, the NHC said Iona had maximum sustained winds around 105 mph with higher gusts. The hurricane reached maximum sustained winds around 125 mph on Tuesday, reaching Category 3 status on the Saffir-Simpson wind scale. Iona is expected to continue moving west, although further weakening is expected Wednesday, followed by "little change in strength" Wednesday night and Thursday, hurricane center forecasters said.

NHC also tracking Tropical Storm Keli, 3 other disturbances in the Pacific In addition to Iona, the hurricane center is also tracking Tropical Storm Keli and three other tropical disturbances in the Pacific. Keli is moving rapidly westward and that motion is expected to continue during the next day or so, according to the NHC, with maximum sustained winds near 40 mph with higher gusts. Forecasters said Keli is expected to weaken to a tropical depression by late Wednesday and dissipate by Thursday. Also in the Pacific, the hurricane center said late Tuesday night, July 29, an area of low pressure located about 1,150 miles east-southeast of the Hawaiian Islands "remain limited and have changed little since this morning." Forecasters said if persistent showers and thunderstorms re-develop during the next day or so, a short-lived tropical depression could still form, as the system is expected to enter the Central Pacific basin shortly. The NHC gives this system, labeled as EP98, a 60% chance of formation through the next 48 hours. The hurricane center also said it is keeping tabs on a trough of low pressure located several hundred miles southwest of the southwestern coast of Mexico that is producing "a large area of disorganized showers and thunderstorms." Environmental conditions appear conducive for development, the NHC said, and a tropical depression is likely to form during the next day or two while the system moves west-northwestward around 15 mph, remaining "well offshore of the southwestern coast of Mexico." Hurricane center forecasters give this system, labeled as EP99, an 80% chance of formation through the next 48 hours. Lastly, an area of low pressure is forecast to develop well south of southern or southwestern Mexico late this week, the hurricane center said. Environmental conditions appear conducive for some gradual development of this system and a tropical depression could develop over the weekend or early next week, the NHC said July 29. The system has a 60% chance of formation through the next seven days. How do hurricanes form? Hurricanes are born in the tropics, above warm water. Clusters of thunderstorms can develop over the ocean when water temperatures exceed 80 degrees Fahrenheit. If conditions are right, the clusters swirl into a storm known as a tropical wave or tropical depression. A tropical depression becomes a named tropical storm once its sustained wind speeds reach 39 miles per hour. When its winds reach 74 mph, the storm officially becomes a hurricane. Prepare now for hurricanes Delaying potentially life-saving preparations could mean waiting until it's too late. "Get your disaster supplies while the shelves are still stocked, and get that insurance checkup early, as flood insurance requires a 30-day waiting period," NOAA recommends.

Hurricane Iona has strengthened into a Category 3 storm: See path
All is calm in the Atlantic Ocean – for now, at least – however the National Hurricane Center is staying busy with the Pacific Ocean, as forecasters are currently tracking five systems, including one hurricane and one tropical storm. The hurricane center said in a July 28 advisory Hurricane Iona has strengthened into a major hurricane well south of the Hawaiian Islands. The NHC said the storm was located about 790 miles south-southeast of Honolulu with maximum sustained winds near 115 mph with higher gusts, making Iona a Category 3 hurricane on the Saffir-Simpson wind scale. Iona is moving toward the west and this motion is expected to continue with a gradual increase in forward speed during the next couple of days, according to hurricane center forecasters, who expect additional strengthening Tuesday night with steady weakening expected to begin by Wednesday. Will Hurricane Iona impact Hawaii? No direct impacts are expected to the Hawaiian Islands. However, AccuWeather reports the increased trade winds combined with "moderate or greater drought conditions across over half of the Hawaiian Islands" will increase the wildfire risk through much of this week. More weather news: What is a derecho? These 'inland hurricanes' can cause tremendous damage NHC also tracking Tropical Storm Keli, three other disturbances in Pacific Ocean Tropical Storm Keli has also formed in the Pacific, with the hurricane center saying in a July 28 advisory that the storm was located about 960 miles southeast of Honolulu. Keli has maximum sustained winds near 40 mph with higher gusts and is forecast to continue moving westward during the next few days. The hurricane center says "little change in strength" is forecast during the next couple of days. Also in the Pacific, the hurricane center said late Monday night, July 28, an area of low pressure located about 1,500 miles east-southeast of the Hawaiian Islands has "changed little since earlier today." Forecasters said environmental conditions appear "marginally conducive" for some development of this system, and a tropical depression or tropical storm could form during the next day or two as the system moves westward. The NHC gives the system, labeled as EP98, a 60% chance of formation through the next 48 hours. The hurricane center also said it is keeping tabs on another "large area of disorganized showers and thunderstorms" located a few hundred miles south of the southern coast of Mexico that is associated with a trough of low pressure. "Environmental conditions appear conducive for development, and a tropical depression is likely to form during the next couple of days," the NHC said July 28, although the system is expected to remain well offshore of the southwestern coast of Mexico. The hurricane center gives the system a 90% chance of formation through the next seven days. Lastly, an area of low pressure is forecast to develop several hundred miles south of the southern tip of the Baja California peninsula late this week, according to the NHC. Environmental conditions appear conducive for some gradual development, forecasters said, giving the system a 20% chance of formation through the next seven days.

"Get your disaster supplies while the shelves are still stocked, and get that insurance checkup early, as flood insurance requires a 30-day waiting period," NOAA recommends. Develop an evacuation plan: If you are at risk from hurricanes, you need an evacuation plan. Now is the time to begin planning where you would go and how you would get there. Assemble disaster supplies: Whether you're evacuating or sheltering-in-place, you're going to need supplies not just to get through the storm but for the potentially lengthy aftermath, NOAA said. Get an insurance checkup and document your possessions: Contact your insurance company or agent now and ask for an insurance check-up to make sure you have enough insurance to repair or even replace your home and/or belongings. Remember, home and renters insurance doesn't cover flooding, so you'll need a separate policy for it. Flood insurance is available through your company, agent, or the National Flood Insurance Program. Act now, as flood insurance requires a 30-day waiting period. Create a family communication plan: NOAA said to take the time now to write down your hurricane plan, and share it with your family. Determine family meeting places, and make sure to include an out-of-town location in case of evacuation. Strengthen your home: Now is the time to improve your home's ability to withstand hurricane impacts. Trim trees; install storm shutters, accordion shutters, and/or impact glass; seal outside wall openings. Gabe Hauari is a national trending news reporter at USA TODAY.
