Red sky at morning, sailors take warning;

Red sky at night, sailors’ delight.

Due to the rotation of the Earth, storm systems travel from west to east in the mid-latitudes. A reddish sunrise, caused by particles suspended in the air, often foreshadows an approaching storm, which will be arriving from the West, within the day. Conversely, a reddish sunset often indicates that a storm system is on the west side (same side as the sunset), travelling away from the viewer. Maya alerted me to the notable sunrise this morning and sure enough the weather service has predicted a significant winter storm for this evening.
