Excessive Heat, Code Red Air Warnings This Weekend

As temperatures climb above 100 and heat index values reach 110+ in Herndon, what you can do to stay cool.

Excessive heat and unhealthy air warnings are in effect for the Herndon area for much of this weekend.

The excessive heat warning remains in effect until 8 p.m. Friday and resumes Saturday from 11 a.m. to 10 p.m.

The National Weather Service says temperatures will reach up to 105 in some areas of Northern Virginia on Saturday. The heat index will reach 110 on Saturday, the service said.

The Weather Channel is warning of possible - probable - severe storms hitting us tomorrow -Sunday. What contingency and response plans are the utilities and our local governments making to deal with it? As one with some medical concerns are there recommendations that those in that category evacuate? Responding to these type of concerns after the storm when communications are totally down is not adequate. I don't think the human toll of this week has been evaluated - thousands of dollars of medicines lost; asthmatic, elderly, children and diabetics in hospital ERs....millions of food supplies destroyed. Let's see some leadership --- beginning at the local micro level in dealing with these preparations. I'm not whining - I'm volunteering my thoughts and whatever skills I have at this and looking for our media, utilities and governments to get out of the reactive mode.
