Just look at that satellite photo of what was at one time category three hurricane Ophelia. Quite impressive to say the least! Unfortunately, Ireland is underneath those swirling clouds and reports are that more than 100,000 people are without power as a result of the storm.

Ophelia transitioned from a concentrated warm-core hurricane to a more spread out ocean storm with energy being derived from the processes of the atmosphere more so than those of heat being drawn out of the ocean – as a hurricane would do. In the end, the results are almost the same: strong wind (possibly reaching hurricane force in some areas), storm surge and high waves at the coast along with periods of heavy rain.

Luckily for Ireland and eventually the northwest portions of the United Kingdom, Ophelia is moving very fast and the low pressure area will fill quickly, bringing a swift end to the storm by this time tomorrow.

Meanwhile, we are watching invest area 92L to the north of Puerto Rico and the Dominican Republic. Right now, it is very disorganized and is likely to remain that way as it moves generally off to the north and west for today and tomorrow followed by a turn towards the northeast as a strong cold front pushes off the East Coast.

Upper level winds and the interaction with the approaching frontal system will mean that 92L has little chance of becoming a tropical storm but it is likely to bring rain and an increase in wind for Bermuda over the next few days.

Outside of that, long range model guidance suggests one more area of interest could develop in about a week to ten days down in the western Caribbean. All of the reliable global computer models show a lowering of pressures in the region as a favorable MJO pattern moves through. This means conditions would be more favorable for upward motion and thus tropical thunderstorms to develop and possibly lead to another storm taking shape. It’s too soon to know for sure if this is going to happen but the signs are beginning to show within the models and as such, and considering the climatology of the region, we should pay close attention over the coming days.

I go over all of this and more in today’s video discussion posted below.


Hurricane Ophelia likely to bring strong winds, rain to British Isles in its post-tropical state

Updated: 8:40 AM ET Oct 12

Ophelia is the 10th hurricane in a row to develop in the Atlantic Basin, something that has not happened in more than 100 years. Fortunately for U.S. interests, Ophelia is far from land and will not be of concern – unless you have friends or family in the British Isles.

Right now, the hurricane is over fairly warm water and as such is maintaining hurricane structure and intensity. Top winds are 85 mph and we could see that increase some today and tomorrow before the hurricane turns more to the northeast and over cooler waters.

As this turn happens, Ophelia will begin to lose its deep warm core structure and transition in to a larger, spread out storm system with heavy rain and near hurricane-force winds as it moves in to the mid-latitudes and towards the British Isles. This will be a high impact event for portions of the northwest coast of areas such as Ireland and the United Kingdom. It is rare to have something like this occur but not unprecedented.

I have prepared a video discussion for today with more details on Ophelia plus a look at the surprise near-La Nina event that we have in place right now; a far cry from the El Nino that many thought was coming for 2017.

Been a really long night – got a lot of equipment set up ahead of Nate. Going to get some rest now – but first, here is a video discussion with the latest info, including a look at the projected storm surge values as well as the heavy rain threat.

Nate nearing hurricane strength as it approaches the Gulf

This is an update written by Meteorologist Zack Fradella:

Tropical Storm Nate is now a 65 mph storm with a pressure of 990MB as of the latest 7 p.m. CT advisory from the National Hurricane Center. The movement is very rapid towards the north-northwest at 22 mph.

Nate is now steadily strengthening and those living in the Hurricane Warning area need to rush their preparations to completion.

As the storm approaches the coast of Louisiana on Saturday evening, a turn to the north is expected and depending on exactly where that turn occurs will determine who sees the greatest impacts along the coast. If Nate stays a little more west of track and moves more into Southeast Louisiania the impacts along the coast into the New Orleans area will be greater, comparatively if the system stays more east then the greater impacts will be along the Mississippi/Alabama coasts.

Due to the fast forward motion rainfall totals are not the greatest concern at the coast, it’s the surge. This area along the northern Gulf Coast from Southeast Louisiana to coastal Mississippi and Alabama is prone to storm surge inundation. Projections are for up to 8-10 feet of surge possible and all of these┬álocations are under a Storm Surge Warning.

Farther inland rainfall could cause flash flooding issues from Mississippi and Alabama up through the Appalachians.

Mark is nearing the coast of Mississippi tonight where he will deploy various pods to track the surge inundation as Nate makes landfall Saturday night.



Live coverage of Nate begins today

9am ET Friday, October 6, 2017

It is time to head down to the Gulf Coast to set up equipment ahead of what is forecast to be hurricane Nate this weekend. From here on out, I will be streaming live from the vehicle cam which is embedded via YouTube below. I will post video discussions along the way but I encourage you to tune in here at 11am ET, 5pm ET and again at 11pm ET as I will go over the very latest info from the NHC live as it comes in. I can explain everything as it is happening – something unique to the live streaming experience.

Also, be sure to look for our app, Hurricane Impact, on the Apple App Store and on Google Play. Search “Hurricane Impact” and have access to all things hurricanetrack related, including our multiple live streams and live weather data – all in one convenient package.
