Tropical update: Jerry’s recurvature is likely, but more waves to watch

/ September 19, 2019 at 8:39 AM

So let’s start with the good stuff: Model agreement has continued to improve regarding Tropical Storm Jerry’s future path, and that path is toward recurvature way from the US East Coast this weekend. (Bermuda, which just took a pretty good whooping from Humberto, will want to watch Jerry with wary eyes.) But, for Charleston, Jerry increasingly looks like a storm about nothing. It is forecast to become a hurricane later today, but will encounter hostile upper-air conditions that will limit its further development, according to the Hurricane Center. This should preclude the stronger solutions and a more southerly track as seen in a few of the global guidance members that we discussed yesterday.

Tropical update: Jerry is named

/ September 18, 2019 at 7:51 AM

Tropical Depression Ten strengthened overnight, having reached Tropical Storm status and the threshold to receive a name. The name most of us thought this system would get was Imelda, but a tropical depression formed quickly near the Gulf Coast yesterday and was named within an hour’s time. Imelda is already inland, so we are now watching Tropical Storm Jerry as it churns in the Atlantic, 960 miles east of the Leeward Islands (and a lot farther than that from Charleston!)

The week ahead: A hint of cooler weather in store

/ September 15, 2019 at 11:45 PM

A warm start to the work week will give way to a taste of fall to close it out. (I mean, my goodness, 82° and fair skies on Thursday? Pinch me!) Plus, no worries about the tropics for the foreseeable future, either. Here’s a look at the week ahead…

Tropical Depression Nine forms as track shifts further east

/ September 13, 2019 at 6:00 PM

We now have Tropical Depression Nine in the Atlantic after a closed circulation was found. It has maximum sustained winds of 30 MPH and it moving NW at 8 MPH. It is expected to become Tropical Storm Humberto tomorrow as it moves very near the Abaco Islands.

Tropical update: Depression expected to form over the Bahamas later today

/ at 8:41 AM

Potential Tropical Cyclone Nine, which is forecast to develop into Tropical Storm Humberto by tomorrow, continues to bring breezy conditions and rain to the Bahamas, who totally need such a thing right now. We continue to monitor this storm for potential impacts to our weather next week, but there is still serious uncertainty that has not yet been resolved in the models. So, we watch and wait.

NHC begins advisories on Potential Tropical Cyclone Nine, possible future Humberto

/ September 12, 2019 at 5:24 PM

The National Hurricane Center has started advisories on Potential Tropical Cyclone Nine. This is a wave that has not yet become a tropical cyclone, but the probability of it becoming one is high enough for NHC to issue Tropical Storm Warnings for the Abaco Islands and Grand Bahama — exactly where they are not needed. If named, PTC 9 would be Humberto.

Tropical update: Another depression looking likely near the Bahamas

/ at 9:29 AM

The National Hurricane Center is watching an area of disturbed weather affecting the Bahamas for potential tropical cyclone development. This wave has been watched closely for the last few days, and probabilities for development have been rising. It now appears likely that we will see a tropical depression form in the next couple days. If it becomes named, it would be named Humberto.

September 10: The climatological peak of the Atlantic hurricane season

/ September 10, 2019 at 9:00 AM

Today is September 10, which marks the climatological peak of hurricane season in the Atlantic basin. Fresh off our brush with Dorian, let’s take a look at where we are and where we might be headed for the rest of the season, which runs through November 30.

The week ahead: Warmth continues, far fewer hurricanes

/ September 9, 2019 at 1:24 PM

The week ahead will continue to feature a late-summer heat wave, especially as we kick off the new work week. Temperatures in the 90s will feel closer to the 100s with humidity with just a slight chance of an afternoon shower or storm to cool things off. Thunderstorm chances kick up as we head into the weekend as a tropical disturbance (more on that in a sec) is set to move through Florida, enhancing moisture in our neck of the woods.

Post-Dorian heat wave for the weekend

/ September 6, 2019 at 12:53 PM

An abnormally strong ridge of high pressure is going to build in for the weekend, keeping rain chances relatively low and temperatures rather high for early September. In fact, the record high of 95° for Saturday is forecast to be at least tied. By Sunday, more humidity works its way in and heat indices may exceed 105°. Aside from an isolated afternoon thunderstorm, relief from the heat looks unlikely. Keep this in mind if you or someone you know remains without power — they’re going to want some air conditioning this weekend!
