Good afternoon, We wanted to get this initial information out to you regarding potential impacts from Dorian later this week. No conference calls are planned at this time. We expect to have more details as this week progresses. *Period of greatest Threat:* Late Friday into Saturday morning *Locations most at risk*: Cape and islands, as well as the adjacent coastal waters *Confidence*: Low confidence overall, especially in regards to wind and rainfall. That will depend on the track of Dorian. *High *confidence in a rip current threat late Wednesday into Saturday along ocean-exposed, south-facing beaches. Rough surf is likely, too. While an offshore track is most likely, it should be noted the average error the past 5 years for a forecast at this time range is *140 miles.* Should Dorian track farther south and east, the wind and rainfall threats would be reduced. The rip current/rough surf threat is almost a certainty. The next scheduled briefing is 5 PM Tuesday, unless there is a need for a briefing sooner.
