Irma may not be having any direct impact on Canada but it's funneling extra moisture into the stationary trough sat over the Avalon, finally a bit of a break in the rain this afternoon (though still heavy drizzle) which has been ongoing since Friday night, and looks like picking back up in intensity through Monday.

Rainfall since Friday thru 3:30 PM:
St Johns Airport #YYT 87 mm
St Marys 82.8 mm
St Johns West 62.5 mm
Cape Race 49.3 mm


Average rainfall here in September is 129mm, so likely to surpass that from this if we get another 60mm by Tuesday as forecast.

Still feel really lucky compared to people in Florida etc, its only a bit of rain here and over 3-4 days shouldn't pose too many problems.

Now if that had been snow... rolleyes.gif

Jose is perhaps going to be a little trouble maker on the precip front once he eventually decides where he's going.

The Irma influence is pretty mute as the stream of tropical moisture was all ready there Fri/Sat/Sun before Irma moved into the picture. Was a perfect set up for prolonged heavy snow here had it been winter, into the 3rd consecutive day of rain here, even in the breaks of heavier rain we are still getting a heavy drizzle not picked up by radar. Should wrap up by Tuesday noon time, would guess would be a total of 160-180mm by then.

On average (1981-2010), St Johns #YYT receives 129.6 mm of rain in September.
Since Friday morning (thru 9:30 AM), 126.2 mm has fallen

Course in winter oceans cooler so wouldn't be the same moisture but an impressive but depressingly wet few days!

Jose perhaps more of a threat to NS, but long way off.

Jose looks another to keep a close eye on, the 12z Euro and CMC has it tracking through Atlantic Canada around the 21st as a powerful storm, probably still a hurricane. The Gfs slams it into the NE US. Long way off at this stage.
