The weather for the start of the work week is expected to be much the same as Sunday -- hot.

For a second consecutive day, the Bay Area Air Quality Management District is calling for a Spare the Air Day for the region on Monday.

The alerts are issued when air district officials expect high levels of air pollution and smog caused by high temperatures and low winds mixed with vehicle exhaust. Commuters are encouraged to take public transportation or carpool Monday and as the alerts continue, possibly through the week.

Forecasters are predicting up to 103 degrees inland Monday. Walnut Creek is expecting a high of 93, with 81 degrees forecast at Oakland International Airport. In the South Bay, a high of 91 degrees is expected, and winds throughout the region will be from 10-15 mph.¿

Temperatures may be some 10 degrees cooler Tuesday.

On Spare the Air days, high levels of pollution can trigger symptoms in people with asthma, bronchitis and emphysema, and throat irritation, chest pain, congestion in others.

"To avoid unhealthy air quality and congestion on Bay Area roads, it's crucial that commuters find a better way to work than driving alone," air district Executive Officer Jack Broadbent said.
