A dayslong October heat wave is set to end Thursday night, when the National Weather Service heat advisory for inland Monterey County expires at 10 p.m.

The advisory covered interior Monterey County and the Santa Lucia Range, the Cholame Hills of southeastern Monterey County, and the southern Salinas Valley, Arroyo Seco and Lake San Antonio areas. Forecasters warned of highs from the mid-90s to near 105, with weak onshore flow limiting overnight relief.

"Despite a couple degrees of cooling from Wednesday's highs, the cumulative heat impacts will continue and a moderate risk of heat-related illnesses continues into Thursday," the Weather Service said in a statement.

The advisory took effect Saturday morning and was initially scheduled to expire Sunday before being extended several times, stretching the spell of dangerous heat across six calendar days.
