Low pressure taking aim at area

Synopsis: A strong low pressure system currently apporaching Baffin Island is slightly stronger than originally predicted. Minimum central sea level pressure expected to reach 979 mb over the Davis Strait early Tuesday. This will slow the eastward progression down a bit, with the main impact over the Davis Strait now expeced to occur Tuesday, and lasting into Wednesday.

Monday...Sunny, then increasing clouds. Possible breezy conditions at times in the Nuuk area, but strongest winds will remain offshore. Northerly winds will be shifting to southerly winds late. High temperatures in the mid 40's.

Tuesday...Mostly cloudy and breezy, with rain likely. Expected arrival time of precipitation between 00 UTC and 06 UTC in Nuuk. Frozen precipitation over the Davis Strait. Strong winds will form first at the mouth of the Hudson Strait, with westerly winds sustained at 30-40 knots from about 03 UTC till 00 UTC Wednesday with higher gusts. Strong northerly winds developing on the Davis Strait around 20 UTC, with winds at that location also expected to be sustained at 30-40 knots with higher gusts. Temperatures will be colder, only reaching to around freezing on the Davis Strait.

Wednesday....The low pressure will be weakening as it moves further east of the strait. However, northerly winds will be slow to die down in the strait, but should gradually weaken throughout the day. Temperatures will be cold, with highs of only 0 degrees C expected.

Outlook...No other major weather systems expected.
