Earl, Fiona and maybe Gaston?

Danielle is racing into the north Atlantic while Earl, Fiona and another disturbance way out off of Africa march westward. So far the pattern of recurvature up the east coast remains in place, but each system is coming closer and closer to the U.S. mainland. Tonight's VIPIR run has Earl's western bands battering the Outer Banks l;ate Thursday into Friday. Fiona is a much weaker system, but it appears she too will recurve east of Florida. There is still some uncertainty with the steering by this weekend so it's too soon to write off Fiona. It will not be in the Gulf this weekend in case you have beach plans in Florida/Alabama. I won't even bother talking about what could become Gaston as it is way,way out in the Atlantic.

Locally, we should see one more day of above normal shower activity before a drying trend sets in bylate Wed. into this weekend. The negative is, fewer showers mean hotter temperatures. Signs of Fall are showing up over the Rockies with temps. in the 40s. Let's get the fronts coming here before any storms can threaten us.

Wow, Fiona is right on Earl's tail. Satellite loop makes it look she's about to pounce him. Is it techincally possible for two storms to merge, and if so, how would that affect either's forecast track?

Lawrence...this has happened many times, mainly in the Pacific where a Dr. Fujiwara discovered an effect where storms will rotate around each other with the stronger storm ABSORBING the weaker storm. Fiona is likely to be gone by tomorrow due to the outflow/shear from Earl and the upwelling of cooler water behind Earl.
