Showers should kick off a relatively cool week

|

A delightfully sunny and warm Saturday afternoon turned violent as fast-moving severe
thunderstorms swept across the metropolitan area between 2 p.m. and 6 p.m. The storms,
packing high winds and hail, left a litter of limbs, branches and power lines throughout
the region. Wind gusts reached 74 m.p.h. at hard-hit DeKalb and 65 m.p.h. in Chicago’s
Rogers Park. Injuries were reported when the storms hit an Evanston art fair, knocking
down several tents while pelting the area with 1-inch hail. Lake Michigan boaters were
also affected by winds in excess of 60 m.p.h. when the storms reached the lakefront.
More showers are expected Sunday but aren’t expected to be severe.

TROPICAL CYCLONE UPDATE: EASTERN PACIFIC HEATING UP; ATLANTIC QUIET

Two tropical storms, Boris and Cristina, have developed in the Eastern Pacific, southwest
of Baja California. The storms are moving west and currently pose no threat to land. In
contrast, the Atlantic Basin remains free from tropical cyclones.
