HEAT WAVE 2013: We're gonna bake this weekend

A high pressure system hanging over the West this weekend is bringing temperatures extreme even for a region used to baking during the summer.

Temperatures are forecast to approach or match records in the southwest. The mercury should hit 117 in Las Vegas for only the third time ever, while Phoenix should see 118 and Death Valley may see 129.

The hottest cities are taking special precautions to protect residents from scorching temperatures. Police are pleading with drivers not to leave babies or pets in their car, and temporary cooling stations are opening to draw homeless people out of the rays.

What's the difference between an excessive heat watch and an excessive heat warning?

Excessive Heat Watch: Watch out! Conditions are favorable for an excessive heat event in the next 12 to 48 hours. A Watch is used when the risk of a heat wave has increased, but its occurrence and timing is still uncertain. A Watch provides enough lead time so those who need to prepare can do so, such as cities who have excessive heat event mitigation plans.

Excessive Heat Warning: It's going to happen! Issued when an excessive heat event is expected in the next 36 hours. These products are issued when an excessive heat event is occurring, is imminent, or has a very high probability of occurring. The warning is used for conditions posing a threat to life or property.
