A tropical wave, not yet an Invest area, is located near 13N 35W at 16/15Z moving westward at 15 knots. The wave currently has limited convection but a large circulation envelope and this system could eventually become a significant entity.

This wave is getting a lot of model support and if the models are correct it is likely not to be a fishspinner.
It's very early now, and this season the models ahve not been really accurate in regards to forecasting cyclonic development and strengthening; but by this weekend folks in the SE US need to be keeping an eye on this disturbance as it enters the Carribean(per the models).

This may be the model support your talking about.

The wave in question was just labelled 97L.
Like I said yesterday it needs to be watched by folks in the SE US.
It's very early, and the trend has been our friend this year (no big storms); but it's the time of the year and that Atlantic ridge set up is leaving florida unprotected.

The model runs are not very encouraging for intensity and location right now. We definitely need to watch this one closely. Checking my preparedness plans now.

Note that Invest 97L now has a thread in the Forecast Lounge for any additional forecasts on this system since this Forum is primarily just to note various features in the basin.
