Henriette weakens; 'westbound train' of storms following

The next cyclone in East Pacific will be named Ivo

By Star-Advertiser staff

LAST UPDATED: 11:58 p.m. HST, Aug 08, 2013

Hurricane Henriette is starting to weaken as it moved into the Central Pacific, where hurricane trackers in Honolulu took over the forecasting and monitoring of the storm. Henriette continues on a track to pass south of Hawaii early next week.

National Hurricane Center forecasters in Florida are tracking two other storm systems behind Henriette -- what NASA called a “westbound train of developing storms” -- that could intensify in the next two to five days.

What's left of Post Tropical Cyclone Gil and Hurricane Henriette may to bring muggy weather, stronger trade winds and an increased chance of windward showers to the islands, especially the Big island, this weekend.

The forecast for Honolulu calls for an increased chance of rain Friday through Sunday.

Henriette is also expected to bring some surf to east shores.

At 11 p.m., Henriette was barely a category 1 hurricane with winds of 75 mph, down from 105 mph earlier Thursday.  Henriette was 920 miles east southeast of Hilo, heading west southwest at 14 mph.

“Henriette appears to have peaked in intensity as the eye is no longer apparent,” National Hurricane Center forecasters said. “The cyclone should continue to gradually weaken through the forecast period as it moves over cooler waters during the next couple of days and then encounters an increase in southwesterly shear and a drier and more stable airmass.”

Henriette should no longer be a hurricane on Saturday and may weaken into a post tropical cyclone by Monday.

A NASA satellite image released Thursday shows two other low pressure systems behind Henriette with the potential to develop into tropical cyclones. The system immediately east of Henriette has a 20 percent chance of becoming a tropical cyclone in 48 hours and a 30 percent chance of developing over the next five days. Another area of disturbed weather about 700 miles south southeast of Manzanillo, Mexico has a 50 percent chance of intensifying into a tropical cyclone over the next two days and a 70 percent chance of becoming a named storm during the next five days. If it does intensify, it will be named Ivo.

The National Weather Service cautions that the margin of error on the 5-day forecast track is about 175 miles in any direction and conditions are likely to change in long-range forecasts.

NASA released a video animation Wednesday from a satellite fly-over of Henriette. NASA's TRMM satellite found 10 mile high thunderstorms near the hurricane's eye wall.

TRMM is able to measure the shadows cast by towering thunderstorms on the northeastern side of Henriette's eye wall and is able to measure rainfall from its orbit in space.

The 3-D animation shows thunderstorms more than 10 miles high in the center of Henriette. These so-called chimney clouds, also called a "hot tower," can play a part in the formation or intensification of tropical cyclones.

To the staff: The 4th paragraph says that at 5 am, Henriette was heading "west west".

They need to pound it into our brains that the storm is coming our way. If they just say "west" the public might think it has a chance of reversing course and moving away from Hawaii. When the storm doesn't affect Hawaii the "forecasters" will let out a deep sigh of relief and say that we "dodged another bullet".

You weren't there for 'Iniki, were you?

Actually I was on Oahu for Iniki. The fact is that since 1950 (when more accurate records were kept) only 2 hurricanes have made landfall (Dot and Iniki both on Kauai). The rest of the islands have never been directly hit by a hurricane or even a tropical storm. It shows how incredibly rare it is for a hurricane, or even tropical strom to make landfall in Hawaii. And yet the media seem to be hyping any storm that gets within 2,000 miles of Hawaii as a threat. I'm all for being informed but to me this is just major overkill.

You forgot Hurricane Iwa in 1982 which was bad for Kauai and Oahu too. True Hawaii has been lucky to not get hit with more devastating storms but they are always a threat. I agree SA needs to filter out their "breaking news alerts" overkill via email but weather should always be respected and major storms bound for Hawaii are indeed an inherent threat.

I didn't forget Iwa. Iwa didn't hit any island directly but yes it did cause some damage. I don't really call it lucky, after all there's a reason most storms fizzle out when approaching Hawaiian waters (wind shear, cooler waters). Depends on what you mean by "threat". When no other island except Kauai has ever been hit by a major storm in the past 60 years, I feel the news coverage is overkill to the nth degree. Just start really talking about it when it's a few days away and it looks like it's likely to be a real threat. Otherwise, stop with the fear mongering and easy weather stories and report some real news (investigative reports are good).

We have figures out how to travel to the moon but yet still no one has figured out how to stop a hurricane? Isn't there a way to make a path of water cooler temporarily to weaken a hurricane's strength? I would think in this day and age something would have been invented to prevent a hurricane from gaining strength.

You forget how big the ocean is and how hard it would be to cool that much water. Best not to mess with nature, there can be unintended consequenses. Besides, we all know none of these storms will hit Hawaii. Hawaii is naturally protected by cooler waters and wind sheer, that's why it's so rare for stroms to directly hit Hawaii.

I totally get that Weather and storms are unpredicatable.. BUT SA you sent me news alerts in bold and red that it had weaken today I will probably get news alerts that it strengthened. Until storms are in our immediate area stop making every burp it makes a news alert. A better reporter would just encourage people to be prepared but not panic until its closer and we have an ideal of the path. Since early this week the projected path has changed probably 2 a day..

They just want you to know they're on top of the story. It's easy work for them and makes them seem smart. After all, we all need advance notice if the winds increase 5 mph and we have 1 inch of rain. Maybe the non-essential city workers will get sent home early again to avoid getting their feet wet.

So now we have 3-D animations of these storms to get the public even more concerned over NOTHING. And yesterday is the first time I heard the term "post tropical cyclone" mentioned in the news. At least the SA can inform us what's the difference between a post tropical cyclone and a tropical depression. I also love how the SA likes to post the full color graphic of each and every strom that comes within 2,000 miles of Hawaii. After all, a picture's worth a thousand words right and it's also a better tactic to install fear and concern in the local populace and show how "educated" the weather analysts are right? Weather covereage here is a joke, if I want to know the weather here I'll look out my window.

I appreciate the notice but take most of what the press puts out with plenty grains of salt . . . http://www.prh.noaa.gov/hnl/cphc has all the info needed to watch the summer storms and Perry & Price will kick in when it's time to panic! However, having spent the week after Iniki on Kauai my routine on June 1st has always been one of preparation. Once everything is checked off the list there is no need to worry untill the hurricane watch is posted (then I clean up the yard and front porch . . .). Another thing we should all be thankful for is how much better the NWS gets every year. Yes they really messed up on Iniki but the odds are much, much lower that this will ever happen again. Maybe next year the Pacific will rate two drones like the Atlantic!

Agree. Although I don't listen to them during normal times, they're the best source of radio info during a disaster. I remember them during the islandwide blackout during the Big Island earthquake a few years ago.

I'd bet my house the hurricane won't hit Hawaii, however the humidity it might bring may make you wish the hurricane hit.

Seems like every hour we need to have a "breaking news" story about these storms that are threatening our life and limb. I'm just SO SO SO scared thanks to the SA constantly featuring the pictures of the storms everyday in their "breaking news" section.
