Merci de ne pas détourner les évaluations #GIEC (Cf fig.7 du SYR explicite).
Ns sommes en pleine sortie de route!

First, climate change has already caused widespread and substantial losses to almost every aspect of human life on this planet, and the impacts on future generations depend on the choices we make NOW.

Maximum sustained winds are near 70 mph (110 km/h) with higher
gusts. Gradual weakening is expected during the next couple of
days.

Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC
and on the web at hurricanes.gov/text/MIATCDAT2.shtml.

WIND: Gale-force and storm-force winds are expected to continue
across portions of Atlantic Canada through early Sunday.

RAINFALL: Fiona is forecast to produce 1 to 2 inches (25 to 50 mm)
of rainfall across portions of Atlantic Canada, with storm total
maxima as high as 10 inches (250 mm) across Nova Scotia, New
Brunswick, Prince Edward Island, and western Newfoundland. Flooding

Near the coast, the surge will be accompanied by large and
destructive waves.
