Friday October 31st 9:15am.. An east-west ridge of high pressure located over the Maritimes this morning will maintain dry conditions for Halloween across the region, but things will quickly deteriorate on the weekend as a low pressure system develops off the mid Atlantic coast. This system will intensify as it moves NE and is expected to track into NS Sunday night then continue NE tracking across eastern PEI during the overnight hours then into Newfoundland on Monday. High pressure builds in over the region on Tuesday then cloud and showers expected on Wednesday as the next system approaches.
Precipitation... Rain should spread into southern NS after midnight tonight then into PEI near dawn tomorrow. Rain will continue through the day on both Saturday and Sunday ending Monday afternoon. There is a chance that a wintery mix of wet snow may accompany the rain Sunday night into Monday as the system begins to pull away and cooler air floods in. The best chance of any snow will most likely be western PEI. Snowfall through NB could be significant and EC continues to have a special weather statement in effect. Rainfall amounts across PEI Saturday through Monday afternoon could also be significant with 25-40 mms possible.
Temperatures.. Normal today then run a few degrees below normal through Tuesday warming up again on Wednesday.
Wind.. Light NW winds today and this evening. Winds will then shift to the NE after midnight tonight then begin to increase becoming strong northerly by Saturday night and continue into Monday morning. Diminishing NW winds expected later MOnday as the storm pulls away. Light NW-W winds on Tuesday shifting to SW on Wednesday.
Hazards with up coming storm.. Heavy rainfall and blocked water mains (leaves) may lead to some street flooding. Plugged building rain gutters (leaves) may also cause some issues. Strong winds could lead to some power issues especially along the north shore and higher elevations. Strongest winds should occur over Northwestern PEI. Storm surge along the north shore may also be a concern during the high tides.
Watches/warnings.. None for PEI at this time but Environment Canada continues with a special weather statement for NB. Any folks traveling over the weekend into NB should be aware of adverse weather conditions expected there.
