Nova Scotia can expect another round of strong winds with this incoming storm, says CBC meteorologist Ryan Snoddon.

Strong southwest winds will ramp up overnight and continue Friday morning and into Friday afternoon. 

There will be widespread gusts in the 80 to 90 km/h range with gusts 100 to 110 km/h likely along the coast and in exposed areas. 

Power outages are likely yet again, so prepare in advance. 

Winds will shift to northwest 30 km/h, gusting 50 to 60 km/h through the afternoon behind our front. 

Nova Scotia will see significant rainfall with amounts ranging from 30 to 60 millimetres and the possibility of higher amounts locally by Friday evening.

With temperatures climbing into the high single digits, and even low double digits, on Thursday — and holding there into Friday — expect significant snow melt and runoff. 

The combination of the melting and rainfall will bring the risk of localized flooding.

An incoming cold front will then drop temperatures below zero very quickly through Friday afternoon and evening.

A drop of 10-15 degrees in just a few hours is looking likely, creating potentially very icy conditions on roads, walkways and untreated surfaces. 

A flash freeze warning is in effect.

Whatever ice does form will linger, as temperatures will remain below zero throughout the weekend. 

Be sure to have the sand and salt at the ready.

The winds are expected to quiet down Friday afternoon.

Friday afternoon, the temperature will drop quickly from near 11 C to –4 C as a cold front moves north to south.
