Re: Major Update: Idalia & Franklin
|
Relatively cool and moist eye at the moment, but pressure is still lower than earlier, with the winds a bit stronger. It should be noted that these winds are from the NW and SE quadrants, recon having not yet sampled what are probably even stronger winds in the Right Front Quadrant (NE).
Worth noting that there may be a little bit of increased shear over Idalia this afternoon. However, this is expected to drop again tonight, along with increased instability from the atmosphere cooling while the ocean remains exceptionally warm.
