Possible low pressure system to arrive late Sunday and all day Monday

Saturday...Partly clouds with winds picking up in the eastern strait to around 30 knots (~15 m/s) in the evening. Temperatures near 0 C.

Sunday...Windy, especially in the eastern strait as a strong low pressure system will move well south of the strait (near the southern tip of Greenland). Sustained winds may be in excess of 30 knots (~15 m/s) from around 00 UTC Sunday to 00 UTC Monday in the eastern Strait. Otherwise expect increasing clouds as a low pressure will begin to effect the whole area late. Temperatures up to a few degrees above 0 C.

Monday...A possible major low pressure system is expected begin to spread clouds and precipitation by 00 UTC Monday. The current forecasted minimum sea level pressure is 984 mb and is currently forecasted to pass directly over the Davis Strait at 18 UTC Monday. Expect southerly winds ahead of the low pressure and then a switch to northerly winds late Monday after it passes. This could provide very windy conditions and rough seas, especially on the backside with the northerly winds as they could be accelerated by the geography of the strait. The exact timing and strength of this system is rather uncertain at this time.
