CHICAGO, July 23 (Xinhua) -- Chicago residents who have gotten used to amiable weather conditions in summer have been bracing for days of heat wave. And the heat wave extended into Saturday and Sunday.
Starting from last Thursday, once getting out of the building, one distinctly feels like merging into an oven, with hot air blowing into the face and sweating all over.
U.S. National Weather Service on Tuesday issued an "excessive heat watch" for the Chicago area for Thursday and Friday, when the temperatures hovered above 90 Fahrenheit, with heat index ranging from 105 to around 115 Fahrenheit.
The last time such a severe heat wave occurred in Chicago was on July 2-7, 2012, when temperatures were on the higher end of the 90s Fahrenheit, and sporadically rose above 100 Fahrenheit.
High temperatures and humidity can lead to serious heat-related illness, local public health officials warned.
Local authorities urged local residents to take actions to prevent falling sick, such as increasing fluid intake, decreasing activities, avoiding direct sunlight and wearing appropriate clothing. Enditem
