Issued 1:16 PM ADT 21 July 2019 Conditions are favourable for the development of squalls with wind gusts up to 50 knots, frequent lightning and hail.

A cluster of thunderstorms currently moving into the Bay of Fundy is tracking southeastward and will affect the marine waters in the Bay of Fundy including Chignecto Bay and the Minas Basin this afternoon. Wind gusts of up to 50 knots are possible with these thunderstorms.
