IMPACTS
*Hazards:
· Heat Advisory in effect from 1 pm Tuesday through 8 pm Weds.
· http://www.srh.noaa.gov/data/MTR/NPWMTR
*Impact 1 :
· The hot weather will likely lead to health related issues for individuals who are the most sensitive to heat such as the elderly and those on certain medications. First responders will likely see a noticeable increase in routine calls and dispatches.
*Impact 2:
· Temperatures in vehicles will rapidly rise…leading to very dangerous conditions for children or animals. Beat the heat, check the back seat.
*Impact 3:
· Lower humidity readings are expected along with light offshore winds and very dry fuels. Fire weather conditions will become near critical as fuels continue dry out. Days when temperatures are above 90 with low humidity often see an increase in new fire starts. Any source of ignition will have a higher likelihood of new starts including: downed power-lines, auto-accidents, construction sites, ag burns that were presumed to be out as well as outdoor barbecues.
