Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Fri Oct 6 2017

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

The National Hurricane Center is issuing advisories on Tropical
Storm Nate, located over the northwestern Caribbean Sea.

1. A non-tropical area of low pressure is forecast to form along a
frontal boundary about 800 miles southwest of the Azores on
Saturday. Environmental conditions suggest the low will then
acquire some tropical or subtropical characteristics, and a
tropical or subtropical cyclone could form early next week. The low
is forecast to drift over the northeastern Atlantic for the next
several days.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...medium...40 percent.

The GEM now brings it very near to Spain as a transitioning cyclone, and at the end of the run shows another tropical cyclone close to Europe.
According to the GFS, the cyclone will be blocked south of the Azores and turns southwestward with fast weakening.

Neat, seems like we may have a Vince analog on our hands if it doesn't get blocked out.

Storms in this region of the Atlantic have always been my favorite. Decent chance this becomes TS/SS Ophelia by Sunday or Monday. Whether it is classified or not will depend greatly on where it can develop sustained deep convection around its center.

Convection has increased with this...Chances for development are going up.

1. A non-tropical area of low pressure is located about 700 miles
southwest of the Azores. This system is beginning to acquire
subtropical characteristics, and environmental conditions are
expected to be conducive for the development of a tropical or
subtropical cyclone during the next day or so while the low drifts
toward the southwest. Thereafter, the atmosphere is expected to
become hostile for further development.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...70 percent.
