If Higos gets close enough, it could change the course of events.
Rough seas expected
In addition to rain, the sea will also become rougher. Large waves and heavy swells could affect a fairly wide area, from Okinawa to southern Japan, even if the centre of the typhoon remains at sea.
It is a system to monitor not only for its winds, but especially for all of its indirect effects: Rain, swells, saturated ground, and increased risks in vulnerable areas.
Effects could impact Canada
Even though the typhoons are more than 10,000 km away, the two systems could have repercussions in Canada. A typhoon’s path, after it weakens and moves across the Pacific Ocean, can alter atmospheric circulation on a larger scale, creating a domino effect across North America.
Downstream effects to North America could mean a strengthening, more persistent ridge in Western Canada, and unsettled weather in the East by the second week of July.
However, the trough axis may be too far east to bring unsettled weather to Ontario, but it should help with the return to–and then remaining in–a cooler pattern.
