Islanders are preparing for yet another blast of winter-like weather that's primed to hit the Maritimes Wednesday morning.

Environment Canada has issued a blizzard warning for the entire province, calling for between 30 and 40 centimetres of snow with winds gusting up to 110 km/hr.

"We are in for quite a snowstorm," said CBC meteorologist Peter Coade.

The snow is expected to begin Wednesday morning with winds picking up through the day and into evening.

Kings County could see rain mixed with snow or a changeover to rain.

Coade warns blowing snow could be a factor until late Thursday and higher-than-normal water levels are expected mainly on the North Shore.

"There will likely be strong surge felt and rafting of ice along the shore … later in the day when atmospheric pressure is lowest and the tide is highest," said Coade.

The P.E.I. Office of Public Safety is warning Islanders to prepare for the storm with at least 72 hours worth of medication, water and non-perishable food in case of power outages.

The agency also suggests keeping a battery-operated or crank radio on hand to hear weather updates.

Residents living near the coast should be prepared for the storm surge and possible flooding.

Civic number signs should be shovelled out as soon as is safe to make them visible for emergency responders if necessary.

Charlottetown's emergency services personnel are prepared for the storm and an emergency plan is in place, said the city in a news release.

Residents should avoid parking vehicles on city streets so that public works employees can plow and remove snow.

Charlottetown Police is advising motorists to plan ahead for travel and lodging and avoid driving if at all possible.
