There is One area of interest in the Atlantic Basin.

Melissa (Subtropical Storm)
Subtropical Storm Melissa is about 595 miles East of Bermuda and centered at 31.9N & 54.6W with Max sustained winds of 65mph and a Min central pressure of 982mb (29.00'"). This system is moving North (010) at about 10mph.


Melissa is continuing to develop and strengthen. The LLC (Low Level Center) is now displaced to the SE of the mid and upper level centers about 20nmi. Also, some weakAnticyclonic outflow in the inner core has developed during the past couple of hours. Both of these developments together suggest that Melissa is continuing to strengthen and may be separating from the elongated par tent cloud that is located well to the East of Melissa.
All of this together suggests that Melissa is trying to transition to a Tropical Cyclone.

During the next 6-12 hours the upper and low level circulation centers are expected to separate as the vertical shear weakens and reaches its lowest value. This should help Melissa transition from subtropical to tropical features and will allow for some additional strengthening.

It is very possible that Melissa could obtain Hurricane status before entering much cooler water and beginning to break down.

A strong cold front is located to the West of Melissa and approaching Bermuda. This feature will begin to accelerate Melissa to the NE during the next several hours. That motion will continue through 72 hours. around 96-120 hour, the remnants of Melissa are expected to move Northward and merge with this front. This will make Melissa fizzle out and the storm will no longer be a stand alone entity.

Elsewhere, tropical development is not expected during the next 5 days.
