UPDATE: 97L was upgraded to TS Fiona at 30/21Z.
Invest 97L was located south of the Cape Verde Islands near 11.0N 21.7W at 27/00Z. This is another system with a rather large circulation envelope with most of the convection currently located to the southwest of the center. Larger systems usually develop slowly, however the SHIPS model brings the system to hurricane strength (Cat I) by Sunday evening (probably more like Monday given an initially slow development rate). Also of interest is that most of the models move the system to the west northwest to northwest almost immediately. Conditions are generally favorable for continued development and tropical cyclone status is possible by Friday evening or Saturday morning.

During the past 24 hours the SAL has had a significant impact on the convection associated with Invest 97L and today the system looks far less organized than it did on Friday. The large circulation envelope is still intact, but with at least another 12 hours of contending with dry air the system is going to take awhile to recover. With a rapid movement to the west, any development is going to be slow.

Invest 97L upgraded to Tropical Storm Fiona at 5PM EDT with sustained winds of 35 knots. Movement to the west to west northwest at 20+ knots (not much of a westerly wind component to the south of the center with such a fast forward speed). West northwest movement should continue for a couple of days and then the system turns to the northwest at a slower forward speed. Convection is still minimal so intensity is not going to increase much - if at all. Current location almost 900 miles to the east of the Leeward Islands.
