NBC Universal, Inc.

The Bay Area is in for dangerous heat and high fire danger to start July.

Here's a look at what you need to know.

Excessive heat warning and heat advisory

Nearly the entire Bay Area will be under an excessive heat warning or heat advisory for eight straight days to start the month, according to the National Weather Service.

The excessive heat warning, which applies to inland locations, went into effect late in the morning on Tuesday, July 2, and isn't set to expire until the night of Tuesday, July 9. Daytime high temperatures are expected to range from the upper 90s to 110 degrees.

Locations closer to the bay and coast will be under a heat advisory during that same time frame, with high temperatures peaking in the lower 80s to mid 90s. San Francisco will also face heat advisory conditions, but only from late Tuesday morning through Wednesday night.

Red flag warning

A red flag warning has been issued for the North Bay interior mountains, Marin and Sonoma coastal ranges, the East Bay hills and the Santa Cruz Mountains, the weather service said.

The warning will be in effect from 11 p.m. Monday until 5 a.m. Friday.

Staying safe during the heat wave

The weather service shared the following heat safety tips and practices.

  • Never leave people or pets in vehicles
  • Limit outdoor activities during the afternoon and evening hours
  • Drink plenty of water and take cooling breaks
  • Wear lightweight and lightly colored clothing

Fire safety

Due to the high fire danger, officials are asking people to refrain from using fireworks and to be extra careful with activities that could spark a blaze.

"The hot and (already) dry conditions will make ignition easy, and rapid fire spread likely," the weather service said.
