Dorian is a tropical storm that formed in the eastern tropical Atlantic ago. Dorian is probably going to head almost straight west-northwest and menace the vicinity north of the Greater Antilles and the Bahamas. This is going to take some time. By the end of the weekend, Dorian will be encountering islands in the northeastern Caribbean as a topical storm, most likely. The chance of Dorian remaining as a storm (as opposed to regressing to a depression) or strengthening from storm to hurricane is not at all large. But, unlike some others storms we've seen lately, Dorian seems to gain a little strength or add a certain degree of organization rather than the opposite. Over the next few days, Dorian will pass over warmer waters, which should strengthen it, but the storm will also encounter win shear and drier mid-level winds, which may weaken it. Here's the thing: If Dorian gets strong enough soon enough, the storm will start to make a bit more of its own weather and survive threats from shear or dry conditions.
So what you say? This storm is days away and has little chance of being a hurricane. Well, that's all true, but there's more.
First, Dorian formed very far east. That is unusual this early in the year. Second, if Dorian becomes a hurricane and had formed this far east the storm will come close to (but not break) some sort of record, or at least be impressive. Third, and this is highly speculative, but there are some models rumored to project Dorian forming a very large hurricane, traveling up the Atlantic coast, menacing (just barely) New England and hitting Nova Scotia. The chance of that exact thing happening are pretty much zero. That would be close to 2 weeks from now, and we simply can not predict what a hurricane is going to do in two weeks.
But the reason this is interesting is that the hurricane tarot cards have a North Atlantic track in Dorian's Future, and it's current track may have Florida in its future. Therefore, we will want to watch Dorian.
If any of this works out, Dorian will be a long-lived hurricane. If warm Gulf waters strengthen Dorian, the storm will then appear younger than it is for a while. Then, at the end, things could get very ugly all of the sudden.
