UPDATE: As of 6:07 p.m., Environment Canada says conditions are no longer favourable for the development of severe thunderstorms.
The Halifax area is back to being under a severe thunderstorm watch.
Earlier a warning was in effect as strong thunderstorm had been 10 km north of Tantallon. That was around 5:30 p.m., but Environment Canada now says it has weakened or moved out of the region.
However conditions are still favourable for the development of severe thunderstorms that may be capable of producing strong wind gusts, large hail and heavy rain, so the watch is still in effect as of 6 p.m.
"Heavy downpours can cause flash floods and water pooling on roads. Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors!" the national forecaster said.
