SYNOPSIS:

For the southern zones, clouds and some light showers to start Thursday, breaking up in the afternoon. This will help drop temperatures by 1-3 degrees today. As for rain, it’s light showers at best and very patchy. An upper SW flow continues with consistent light to moderate winds. Strongest gusts will be in the Fraser Valley once again, with gusts maxing out around 25-30 km/h. As the trough continues to move north instability continues this afternoon and over the next couple of days. Thunderstorms look to develop through Manning Park and the Coastal Mountains again today and possibly on Vancouver Island around the Campbell River area. Any storms that do develop will have little to no precipitation with them so the risk of new starts is high as lightning will be dry..

OUTLOOK: Saturday to Monday

A trough of low pressure will bring clouds over a good portion of the Coastal Fire Center, helping drop temperatures to seasonal and increasing relative humidity (RH) values. On Saturday, the offshore low will start to move close to Vancouver Island and will help push in sub-tropical moisture as well as instability. This low along with the current trough basically become one feature. Storm potential increases with Vancouver Island as well as the Sunshine and North coasts seeing widespread storms Saturday night. These storms are expected to be accompanies by rain as they’ll be tapping into more sub-tropical moisture. Temperatures will see a downturn for the weekend and a rise in RH values. It will start drying and warming up to start next week.

NOTE FROM TIVFD

We are still in Extreme, but if all goes well precipitation-wise, we may be able to drop to HIGH on Monday. Keep checking the website, the ferry line Fire Board or e-Spokes for updates.
