Conditions to Improve

Conditions will begin to improve during this forecast period, with winds and wave heights decreasing and the winds picking up a more easterly component. There is a low pressure system in the Northwest Atlantic that has a long front trailing it that will warrant further discussion in the coming days.

High pressure is centered over 30N, 40W today giving you easterly flow on the large scale and temperatures in the mid-70’s. The closest ASCAT passover is just to your east, but it also shows predominantly easterly to east-noreasterly winds at 10 to 20 knots. There is a low pressure system just off the eastern tip of Newfoundland which is kick up waves and also has a trailing front that extends all the way down to the Bahamas which we will want to keep an eye on.

Looking to the forecast, the winds and waves will begin to decrease over the next 24 hours though their direction should remain fairly consistent. The winds will begin to become even more easterly at the end of the forecast period – Hooray! It is still hard to predict the currents since, as your observations have helped us discover, they can’t be trusted when weak in the model. You are still on track to approach the southern edge of a clockwise gyre at around 38.5W which should give you easterly currents but that looks like it’s still two or three days out. As far as I can tell, the clouds will be scattered to half coverage but the weather should be fairly dry.
