Olivia nearing Hawaii as we track Isaac and Florence

Hawaii is preparing for another encounter with a tropical cyclone as TS Olivia continues to move towards the island chain. The main issues will be the threat of flooding rains which could result in mudslides, flash flooding and road closures. It’s possible too that some portions of the islands will see tropical storm force winds which could result in minor damage but Olivia has weakened considerably and will continue to do so.

Meanwhile, Isaac is maintaining its strength just below hurricane intensity as it tracks westward toward the Lesser Antilles. It is possible that it will regain some intensity and become a hurricane again before stronger upper level winds halt development, just as it is moving through the eastern Caribbean.

And then we have Florence which has weakened just a bit overnight due to complex changes within the core. Warm sea surface temps ahead and fairly ideal upper level winds mean that Florence could reach category five strength at some point.

A hurricane watch and storm surge watch are now in effect from Edisto Beach, SC to the NC/VA border. The time to move preparations along is at hand and people within the watch area need to have those preps complete by sundown tomorrow.

I have posted my latest video discussion for this morning below. I’ll have another updated video discussion here this evening. Follow along too on Twitter: @hurricanetrack as well as our iPhone app: Hurricane Impact.


Florence intensifies to category four; may become a category five

The news is not good at all concerning hurricane Florence. The NHC reports that winds are now near 140 mph and additional strengthening is expected. It is possible that Florence could reach the dreaded category five threshold at some point.

The main thing to keep in mind for right now is that Florence will be an enormous hurricane with a huge wind field. This will push a deadly storm surge in to the coast as well as spread hurricane force winds inland a good distance. It is also obvious that the rain threat will be significant as well, resulting in another major flood disaster for portions of the Mid-Atlantic.

I have prepared an afternoon video update on Florence and the other systems we are tracking. I will post another video discussion and blog update tomorrow morning.

Extremely busy time in the tropics – just as the peak of the season arrives

It is September 10 and the peak day of the Atlantic hurricane season from a climatological perspective. We have a lot going on out there and the risk to people from Hawaii to the Lesser Antilles and eventually parts of the Southeast U.S. is increasing as Olivia, Isaac and Florence track closer to land. We also have to monitor a new system trying to develop in te NW Caribbean Sea which could impact the western Gulf region later in the week. I break it all down in my morning video post below.

I will post another update after the 5pm ET advisory package is released from the NHC.

Late afternoon video discussion

There is so much going on out there that it is mind-boggling. Not only do we have Florence to contend with, but now a new area to monitor coming out of the NW Caribbean Sea towards the Gulf of Mexico.

Of course, in the central Pacific, we’re tracking Olivia as it moves steadily closer to Hawaii.

Then, Isaac which is almost a hurricane; poised to bring hurricane conditions to portions of the Lesser Antilles this coming week.

As for Florence, well, it has the makings of an epic disaster that could define a generation for portions of South and North Carolina, depending upon where the center crosses the coast, how strong it is and how much rain it dumps after landfall.

I go over the latest in this rather somber but honest discussion about what’s at hand.
