0z EPS is slightly more aggressive with this wave, with about 40-50% of the members showing a low. Wide spread from Caribbean to the Bahamas.

This run also shows some support for the following wave, on a much more clear-cut recurve pattern (even earlier than Erin), but pretty weak in both support for development and intensity.

DEEPMINDS UPDATE:

Erin expected to peak as a Cat 3-4, safe recurve for the CONUS but Bermuda needs to watch out

"Fernand" remaining a weak TS into TX (98L) and could be a category 1

"Gabrielle" becoming an OTS CV recurver (major)

"Humberto" forms in the WCAR and vomits in the Gulf (major landfall)

Followup: this looks like an AEW preceding the one the last two UKMET runs had with a TD forming 200 miles E of Guadalupe
