Sep 29th: Imelda and Humberto Update

It isn't that often that you see two storms spinning so close off of the Southeast coast of the US but Imelda and Humberto are putting on quite the satellite show today:

As we mentioned in our weekend blog updates, the slower forward motion of Imelda allowed Humberto to catch up to it and eventually sling shot it eastward and out to sea, fortunately preventing a US landfall. Unfortunately, this means Bermuda is now in the path and should begin their hurricane preparations asap as they are now under a hurricane watch:

Imelda did bring over 7" of rain and a wind gust to 47 mph at our Blue Lagoon Island Weatherstem on Sunday:

 

The biggest impacts from Imelda across the Southeast US will continue to be elevated surf and rip current risks as the combination of Imelda and Humberto will keep the ocean stirred up through the week:

You can see the red flags flying and rough surf from our Jacksonville Beach Weatherstem station earlier today: 

   
The waves will stay elevated throughout the rest of the week:

As we approach October, we start to shift our focus from the Main Development region to the Caribbean and Gulf of Mexico. You can see the shift from the beginning of the month to the end of the month below:

Right now, there's not too much to be concerned about after Imelda and Humberto move away but both the GFS, Euro, and Google AI ensemble show a potential wave in the MDR by around October 8th or so that we will need to watch:
