Emily, Franklin, and Coriolis
Storm Track is watching Emily and Franklin. And there is also the NOAA site, which you are paying for.
As these lows, deriving from the north African coast, move north of the equator, the air surrounding them begins to spin, due to the coriolis effect of the earth's rotation - counter-clockwise in the northern hemisphere, clockwise in the southern hemisphere, and not at all near the equator. Contrary to the old-wive's tale, the coriolis effect does NOT determine the direction of rotation of water down the toilet.
