Rainfall warnings : Weather could mean flooding for parts of P.E.I.

'Messy mix' of weather could mean flooding for parts of P.E.I. this weekend

Snow began to fall midday Friday in Charlottetown, will change to rain in evening

What could be a treacherous weekend for travel in P.E.I. began with light snow flurries around midday Friday, but that precipitation is expected to change to rain by the evening.

Environment Canada issued a rainfall warning for Prince Edward Island's Kings and Queens counties early Friday morning, upgrading the weekend storm situation from the special weather statement it had issued Thursday.

The agency expects anywhere from 25 to 35 millimetres of rain to fall, which combined with melting snow could cause localized flooding in some areas because the frozen ground is unable to absorb the excess water.

Environment Canada said rain will begin Friday evening and continue until around noon on Saturday.

CBC P.E.I. meteorologist Jay Scotland said Friday will be a "messy mix of wet flurries and patchy freezing rain."

On Saturday, he said the rain will transition back to snow, and freezing rain and ice pellets will also be possible.

This could all lead to flooding, particularly in eastern and central P.E.I. where heavier rain is expected, he said.

"Be prepared for water pooling on roads tonight through Saturday morning and keep an eye on your basement if it is prone to leaks," Scotland said.

Temperatures to dip Saturday afternoon

There could also be icy surfaces on Saturday.

"As the temperature falls on Saturday, please be cautious driving or walking as wet surfaces will quickly begin to freeze," said Scotland.

Blowing snow could also be an issue for exposed areas, he said.

Environment Canada was suggesting homeowners clear their storm drains and gutters of ice and other debris before the heaviest rain arrives.
