Guillermo closes in on Hawaii, Tropical Storm Watches issued for The Big Island and Maui

Posted in UncategorizedTagged , , , , , , , , Leave a comment

As newly downgraded (but still threatening) Tropical Storm Guillermo makes its way closer to the Hawaiian Islands, the Central Pacific Hurricane Center (CPHC) in Honolulu has been cranking away its newest advisories.

WEATHER 360 ISSUES A LEVEL II, ELEVATED ALERT FOR THE BIG ISLAND AND MAUI AS CPHC ISSUES TROPICAL STORM WATCHES.

The newly issued Tropical Storm Watches for the two furthest east counties in Hawaii mean there is a potential for Tropical Storm conditions to occur in this area over the next 48 hours.  A Tropical Storm Warning means there is a certain level of certainty (normally fairly high…) that a Tropical Storm will impact said area within 36 hours of the statement made.

The following is the Tropical Storm Watch issued by the CPHC for The Big Island and Maui County:

Hurricane Guillermo expected to impact Hawaii

Posted in UncategorizedTagged , , , , Leave a comment

UPDATE 1:00 PM PDT:

Now category two Hurricane Guillermo is now expected to impact the Hawaiian islands as either a mid grade Tropical Storm or as a weak category one storm.

We will update you shortly after this storm crosses over into the CPHC’s area of responsibility over the next few hours.

Tropical Storm Guillermo forms and is expected to cross paths with Hawaii

Posted in UncategorizedTagged , , , , , , Leave a comment

AS OF NOON JULY 30 EDT:

The National Hurricane Center has recently  upgraded former Invest 91-E to Tropical Storm status.  This newly formed Tropical Storm is expected to become a hurricane over the next day or two in the Eastern Pacific.  At the moment, nearly all the major spaghetti computer models are pointing at impact with Hawaii somewhere in between eary morning August 4 Hawaii Time, to somewhere around midday August 6 Hawaii Time.

The intensity computer models are not so sure though on the exact strength of this storm at the time of contact with Hawaii.  A few computer models suggest a potential Category 3 storm with winds surpassing 115 MPH.  And a few suggest a strong Tropical Storm with winds of about 60 MPH.  With all the current information we have, Weather 360 can start to assume that at the time of impact (which is still not 100%), Guillermo may be somewhere around the mid to high  Category 1 area, wth winds of around 80 MPH.  At the moment the NHC has forecasted winds the day before potential impact to be around 65 MPH.

Remember though, at any time all forecasts could shift tremendously, so nothing is ever 100% sure in the world of weather forecasting, especially when it comes to the longer range ones.

We will continue to keep everyone updated on the newly formed Tropical Storm Guillermo.

Computer models pointing to the rapid development of Invest 91-E in the Eastern Pacific

Posted in UncategorizedTagged , , , , , , , , , , Leave a comment

AS OF 9:30 PM EDT 7/28/2015

The National Hurricane Center in their most recent update on the Eastern Pacific indicates the growing support among the computer models of a rapidly growing storm in the Eastern Pacific.  At the moment, the National Hurricane Center has odds of development for this storm over the next five days at 90%, an increase of 20% in two days, along with the odds of development over the next 48 hours up to 30%, up 30% from two and a half days ago.

Why would this tropical disturbance develop if the last one to develop failed so miserably?

First of all, this time around, the shorter range computer models did not really at one point indicate that former Invest 90-E (now weakening Tropical Depression Eight-E) would develop into a massive storm, but this still does not give reason to why Invest 91-E would develop.  The reason for the increased odds of development for Invest 91-E (as opposed to Invest 90-E) is due to the warmer waters.  Invest 91-E is further to the south than Invest 90-E was at the same longitude.  This along with the fact that the ridges of high pressure steering this storm bring it into an area where wind shear (upper level winds that tear off the tops of Tropical Cyclones), is relatively at the point where there is close to zero of this phenomena.

All the ingredients are at the moment seeming to come together for what could potentially be a much larger tropical event than of its most recent predecessor, former Invest 90-E.

So for more updates regarding this storm system, stay tuned to Weather 360, and for emergency information, contact your Local Emergency Management Office if you are in the path of any current, or future storm.

Tropical Depression Eight forms along with Invest 91-E in Eastern Pacific

Posted in UncategorizedTagged , , , , , , , , Leave a comment

As of 1:00 PM Eastern Daylight Time

Not only does Hawaii have to worry about a potential Tropical Depression (which now appears not to be very likely at the moment), they now have to pay attention to yet another potential storm heading for Hawaii, but this time, there’s more fuel.

So what’s happening with this new Tropical Depression?  Computer models can flip-flop positions rapidly, in turn, creating a broad area of obscurity behind all computer model generated forecasts, so what may have appeared to be a large potential storm yesterday, now appears to be a little storm that will clear the way for another potentially larger storm (currently named Invest 91-E).

Wait… what??!?!?!?!?!?!!?!??!?!!?

If you are currently thinking about the ‘potentially large storm to impact Hawaii’ we were talking about yesterday, you may be wondering if we had these two storms confused, and the truth is, not necessarily. Over the past few days we have had more and more indicators of two storms developing, but up until last night, the first storm was still expected by the majority of the computer models to be the stronger one.  Although this was only until last night, this is fairly common in the confusing and misleading world of computer models, where long range models tell half of the story, then discarding of the story once  the short range modes begin to pick it up, then right before a storm both of the types of computer models begin to suggest their original stories. (Sounds very similar to current popular YouTube theories on a game constantly pushing weather-related YouTube videos further and further down the most watched list…)

Okay, back to our main point…

How about this Invest-91 E thing, all I wanna know is if this storm’s gonna hit Hawaii.  I know, right?  Invest 91-E, Invest meaning the people at the NHC will start to pay more attention to this storm, is a rapidly developing cluster of thunderstorms in the south-central Eastern Pacific. A mouthful, we know…  Anyways, this disturbance is moving to the west-northwest at around 15 MPH, and will be situating itself over the warmer Pacific waters as it makes its way to the Hawaii area.

Currently, this storm does have the potential to impact Hawaii as some sort of tropical entity.  So for those with interests in the United States’ only state made up entirely of islands, stay tuned for more information, and on our Why Weather360 page, we will now clarify what exactly we cover in our forecast zone.

Feedback is always appreciated here at Weather 360!

Hawaii Hurricane Soon?

Posted in UncategorizedTagged , , , , , Leave a comment

WEATHER 360 IS RECOMMENDING AWARENESS FOR THE FOLLOWING POTENTIAL STORMS IN HAWAII.

At the moment, several different computer models are still forecasting what could potentially (emphasizing potentially here), be a significant hurricane or other tropical entity landfall.

WHAT?!?!?!?!?

Before anyone goes crazy with the explanation points, Weather 360 would like to continue to emphasize this is only one of many potential scenarios involving two areas of interest in the Eastern Pacific moving over into the Central Pacific area.

Still, what!?

According to the European computer model (Euro or ECMWF), the top computer model in the world in terms of forecasting, at least one of these disturbances moving west-northwest from the Eastern Pacific Basin may develop into a full fledged hurricane, one of which may have its potential eye set on the islands of Hawaii.  With the latest computer model run from the ECMWF, we can once again get a knew perspective on this potential storm(s).  In this new computer model run, one will be viewing a hurricane forecasters (potential) nightmare. With a pressure below 960 millibars, indicating a potential category 3 storm pre-landfall, this storm could have winds exceeding 120 MPH.  If this storm was to make landfall in the state of Hawaii, it would be one for the history books, this storm would go along the not terribly long list of major hurricanes to impact the islands of Hawaii.  Although only one major computer model is depicting this (again), potential storm, the reason Weather 360 is focusing in on this event is because the ECMWF is normally known for playing down major tropical events and changing their forecasts rapidly, and this storm has been suggested by the ECMWF for nearly a week.

I know this is the ‘best’ computer model for accuracy, what do the other computer models say?

Well, just recently (meaning over the past day or two), the GFS (known as about the 2nd ‘best’ computer model) along with many others, have been continuing to key into several variations of this scenario.  One of which includes the first and the second storm system impacting the state as Tropical Storms.  So, for those who may happen to be in Hawaii, or those expected to be there shortly, stay tuned for more updates, and for emergency information on this event, contact your local emergency maganagement office or the NHC (The Honolulu Center for Hawaii).

Post-post…:  Weather 360 will now cover any tropical event that may impact the U.S., whether it be Maine, or Hawaii.

Thunderstorms expected this coming weekend initiates a Level III Alert for the NYC Area

Posted in UncategorizedTagged , , , , , , , , Leave a comment

At this time, a Level III Alert is in effect for our area.  This means there is a possible potential threat soon for our area.  This alert does have the potential to become a Level II Alert if conditions expected over the weekend continue to be expected, and if threatening conditions become imminent, there is the potential for a Level I, Most Urgent Emergency to replace the Level II Alert over the next 36 hours.  It is advised that those who may be affected by the potential threat be alert and aware of upcoming forecasts and advise given by your local Emergency Management Office and your local Weather Service Office.  According to the National Weather Service in New York, along with some computer generated models, there is the potential for thunderstorms to move into this area over the weekend.  For more information, view the latest post here at weather360.net, or one of our latest Weather Broadcasts at our Weather 360 YouTube channel.  For emergency information, visit weather.gov or your local NWS’s page for tips and forecasts.

Potential hurricane may impact the state of Hawaii

Posted in UncategorizedTagged , , , , , , , Leave a comment

Over the past several computer model runs, the European Computer Model has consistently shown a disturbance forming in the Eastern Pacific that would make its way to the west-northwest over a period of several days that may render Hawaii as a potential target for this sub-995 potential millibar storm.  Although we are emphasizing the fact that this is only a POTENTIAL scenario, it is best to be alert and aware for anyone either in or going to the Central Pacific state of Hawaii.

For more information you may rely on us here at Weather 360, but please, for emergency information, please rely on the National Hurricane Center and Weather.gov, along with your local emergency management office in the event of a potential landfall.

We’ll keep you updated on this event as time progresses.

Rain and thunder moving in over the weekend could pose a threat to millions

A LEVEL III ALERT MESSAGE BY WEATHER 360 WILL BE RELEASED TOMORROW MORNING AS A PART OF OUR NEW 3.A.S. SYSTEM

The next few days across the Tri-State Area will be for the most part, calm.  With temperatures in the mid to upper 80’s and little to no clouds in the sky, the next few days will feel like true Summer, unlike the temperatures from several days ago that made everyone feel like it was May again.  Although temperatures will be roughly the same during the start of next week, the potential for rain and thunderstorms will start to appear starting around early or midday Sunday.  Therefore, over the next 24 hours, Weather 360 will initiate its first issue of the 3.A.S. (3-Leveled Alert System.)  In this case, an Increasing Level III Alert will be issued as of tomorrow morning.  This means not only to be alert and aware that potentially threatening weather may move into our area over the next 36 hours or so, but also means that the threat level will likely increase to either Level II, or potentially a Level I, Most Urgent Alert.  If this alert was only a normal Level III Alert, then the threat level would likely not increase and one would only have to remain aware of the incoming weather conditions.

Weather 360 introduces a 3-Level Alert System as severe storms target the East Coast

Posted in UncategorizedTagged , , , , Leave a comment

Along with a stream of Weather Broadcasts on our YouTube channel, Weather 360, we would also like to release and test a 3-Level Alert System, which we have abbreviated 3.A.S (not purposely based on E.A.S, which is the NWS’ Emergency Alert System), in which Weather 360 outlines threats on a 3 leveled system that places different types of alert at either of the following;

Level I:  Most Urgent

Level II: Elevated Alert

Level III: Alert

Guidelines for the Alert System

Level I situations:  This event must be within the next 24 hours and may either have a watch or warning from the NWS associated with it or is expected to have a watch or warning shortly.   This event is expected to pose a potential threat to an area and is classified as Most Urgent.  In these situations it is always best to gather last-minute supplies for the storm.

Level II situations: This event must be within the next 48 hours and could pose a potential threat to an area.  Depending on the event, a watch may already be issued for this area.  If your area is given a Level II Elevated Alert, the time is now to be on your way to preparation for the potential threat.

Level III situations: This event must be within the next 72 hours and has the possibility to pose a potential threat.  Depending on the event, a watch may already be issued for this area.  If your area is under a Level III threat, now is the time to start preparation for the potential threat.
