Heat wave warning issued in Bay Area

The National Weather Service has issued an "Excessive Heat Watch" for Wednesday and Thursday, warning that the Bay Area, including the Santa Clara Valley, can expect a dangerous heat wave.

Thursday's predicted high temperature in San Jose is expected to be a record-breaking 97 degrees Fahrenheit; Morgan Hill will likely reach 100 degrees. High temperatures in the 90s are expected even along the coast and may persist through the end of the week.

Remember to drink plenty of water during hot weather. The particular danger of this sudden and early heat wave is that our bodies have not yet acclimated to the heat; a 100-degree day in May feels much hotter than a 100-degree day in August. Be careful when working outdoors over the next few days, pace yourself, drink plenty of fluids and take a break when you feel you need to. Limit arduous outdoor activities during the heat wave if possible.

In addition, the potential of fire danger also will be high. Relative humidity can drop to between 10 and 15 percent during the heat wave. Adding to the fire concern, moderate offshore winds are expected Wednesday night into Thursday morning. North-northeast winds will gust from 40 to 50 mph, which will further dry local landscape.
