Santa Clarita Valley residents who were figuring the current heat wave can’t last might have to reconsider: No relief is in sight, National Weather Service forecasters said Monday.

Monday’s highs were recorded at 107 degrees in Newhall Pass just before 4 p.m. and 108 in Saugus at the same time. Triple digits are forecast for the rest of the week, with the lowest temperature expected to be 100 degrees on Wednesday.

Fire danger was high in the Santa Clarita Valley, and the National Weather Service issued an excessive heat warning and flood advisory for the area Monday.

Flooding occurred across portions of Highway 138 near the Los Angeles County line, and rain fell along the northern slopes of the San Gabriel Mountains on Monday.

“Above-normal temperatures will continue through the week, peaking again over next weekend,” forecasters said in a hazardous weather outlook Monday.

Monday’s highs marked the eighth consecutive day of triple-digit temperatures in the SCV.

According to data from Newhall County Water District, which has recorded temperatures in the valley since 1984, there have been four previous heat spells of eight consecutive triple-digit days in the past 28 years.

If the weather service forecasts prove accurate — and many local residents say they are, if anything, conservative — the current heat wave could break the record of 12 consecutive days of triple-digit temperatures set between Aug. 7, 2003 and Aug. 18, 2003.
