The GFS is creating quite a bit of excitement by developing a tropical storm and moving it up the coast towards Srn CA next Sunday through Monday. While fun and exciting to talk about it must be loudly stated that no other mdl agrees with this forecast even the AI version of the GFS. The EC and and AI version of the EC keep this system well to west of the area. There is a slightly better chc that the storm will pull enough moisture up into Srn CA that it will trigger some showers - still even this scenario only has about a 20 percent chc of occuring. The most likely affects of this system will be more humidity and strong strong south swells.
