Environment Canada has issued freezing rain and rainfall warnings for New Brunswick — which could result in localized flooding in some parts of the province.

Northwestern, eastern and parts of central New Brunswick are under a freezing rain warning, as a low pressure system slowly approaches the province on Monday, bringing mixed precipitation.

The weather agency said the heaviest accumulation of freezing rain is expected in the north, where up to 15 mm of freezing rain is possible.  

Meanwhile, CBC's weather centre noted some areas in the northern part of the province could also see up to 30 mm of rain.

"The precipitation will start as ice pellets, flurries or showers today and then change to freezing rain tonight and persist into Tuesday," Environment Canada said in a statement.

Alert Ready, the national emergency system that already sends alerts to television and radio, will soon be sending them to mobile phones too. 1:46

A rainfall warning is in effect for the Fredericton, Grand Lake, Grand Manan, Saint John, St. Stephen and Sussex areas where up to 40 mm of rain is expected.

Environment Canada said combined with melting snow that's already on the ground there is the possibility of localized flooding.

"The bulk of the rain will be clear of the Maritimes by Wednesday morning though there will be lingering cloudiness and scattered showers/flurries in the wake of the low throughout the day," said CBC's weather centre.

Thursday will be mostly cloudy with isolated showers or flurries.

Environment Canada said surfaces such as highways, roads, walkways and parking lots may become icy and slippery.

The weather agency also said poor weather conditions could contribute to transportation delays.
