Watching ex-Dorian very closely while Flossie nears Hawaii with heavy rain

The remnants of Dorian, labeled as 91L, are flaring up again today with quite a bit of deep convection noted in satellite imagery. However, surface pressures in the area are very high, near 1015-1016 mb and are not falling apparently. I think what we have is a vigorous tropical wave with perhaps a mid-level circulation. While it’s possible for the system to make enough of a comeback to be designated a tropical storm again, I think the odds are against it. Upper level winds are not going to let up enough and the background pressures are just too high.

With that being said, the wave of low pressure will bring showers and gusty winds to portions of the southern Bahamas, Cuba and south Florida over the next few days.

Looking at Flossie today, most of the deep convection has fizzled out which means the threat of heavy rain and strong winds is diminishing. There will still be periods of torrential rain as the bands from the storm move across the islands of Hawaii today and tonight. Any increase in deep thunderstorms will also bring some gusty winds down to the surface but I do not see any widespread issues with this system as it encounters cooler waters and less favorable conditions overall. Flossie will be out of the region by later tomorrow.

Elsewhere in the east Pacific, another area of disturbed weather has developed well to the southwest of Mexico. It will probably go on to develop in to a tropical storm over the next few days as it heads generally westward over the open Pacific.

Tomorrow, I will be working with Mike Watkins of Hurricane Analytics and our long-time friend and colleague to test much of our equipment that we’ll be using this season. He is flying to Wilmington, NC today from Florida to assist with the testing. We plan to set up and test our Surge Cams and a weather station for at least 24 hours. We’ll do the testing along the NC Outer Banks where the wind is nearly constant. It’s also a good area to simulate field mission conditions and to make sure things are running smoothly in an area that may be impacted later this season – you never know.

We’ll stream the entire event live on our public Ustream channel. In fact, I will change the homepage here tomorrow morning to the one we use during our field missions. It will have a live Ustream player console for both the live Tahoe cam and our live Surge Cam during the testing. As I stated back in March, we are dedicating one of our live streaming Surge Cams to public access this season. The other three will be reserved for our subscribers but we felt it was important to share with the public as much as we can at no cost. With the support we have from our members, we are able to do that this season and thus provide access, at no cost, to one of our live streaming Surge Cams.

In addition to the live video that we’ll be testing, we’ll also test the Surge Cam for our Hurricane Impact app. This cam is separate from our live edition. It is the same equipment but instead of live video, users see a live web cam image every 60 seconds. We will be setting up the Surge Cam for the app on this trip so anyone who has Hurricane Impact on their iOS device should check it out. We’ll also have the GPS tracking enabled so you can see precisely where we placed the cam.

Last but not least, for our app users, we will also test out one complete weather station along the Outer Banks. You’ll be able to monitor wind, pressure and a live web cam image within the app under the weather data section.

So if you’re bored tomorrow, join in and take a ride with us on our Ustream channel or right on the homepage of the site as Mike and I head out to the Outer Banks for this important round of testing. We’ll be live beginning around 10am ET and go through until late tomorrow night. We’ll pick up again Wednesday morning right on through late Weds night once our testing is complete.

I’ll have another blog post late tonight to update things on Dorian’s remnants and Flossie in the Pacific.
