 Here's more of what you need to know to start your day. Yeah, heat advisory in effect for the peninsula today from either 10 or 11 a.m. this morning, depending on where you are, until 8 o'clock tonight. And the what of it is? Well, heat index values could get up to 109 for today. And, in fact, that's expected that it could get as high as that. It's certainly into the triple digits. It's just a matter of where it will settle. All right, sunset, 825 on the coast between 827 and 830 inland. A UV index at 10, putting it at very high to extreme category.
