Weather Bomb Blasts the Maritimes!
This surface map clearly shows a well developed storm that can be categorized as a wather bomb due to its signature pressure drop.

When things settle down at the weather centre, I like to browse the weather records. If we’re going to go to the effort of compiling data, we might as well make use of it right?
I like to compare our weather from one year to the next. One year ago today, the weather was lovely, or at least very mild! It stayed mild until the 8th…that’s when the weather bomb blew into town.
Officially, a “weather bomb” is a rapidly deepening and intensifying storm with a central pressure that drops at least 2.4 KPa in 24 hours.
While that’s one weather term that is often misused, on December 8th 2011, that’s exactly what we got. A very intense storm tracked from Cape Cod through the Bay of Fundy into the Gulf of St. Lawrence. A day later it moved across southeastern Labrador. The bomb featured heavy snow in northern New Brunswick- as much as 25 cm; pounding rains - to the tune of 70 mm in Nova Scotia and a messy mixture of weather in between. Winds reached 100 km/h in all four Atlantic Provinces and included some hurricane-force gusts. Power outages were widespread and affected several thousand customers. Schools and transportation services were closed. Stores also shut down amidst flying debris. It was quite something!
Not every storm is a weather bomb, but last December 8th, a text book weather bomb did blast the Maritimes.
