Map of the week

This “forward trajectory” wind map shows where winds from Southern California are predicted to travel over the next five days. You’ll see they pass through the mid west and up into Manitoba. Forward trajectories also show winds arriving on the Prairies from Mexico, Texas, Kansas and other southern regions this week. South central U.S. is a common area where aster leafhoppers and diamondback moth winter in large numbers. These insects are often carried into Western Canada in spring and summer when the south winds arrive. Source: Owen Olfert, AAFC
