Today’s Storm Unstable, Rain Potential Unknown

Today’s storm is expected to drop at least one inch of rain on Glendora, but the unstable storm could bring conditions to areas of the foothills with up to four inches. We may also see a chance of thunderstorms this afternoon.

This information was relayed to GCN by Glendora City Manager Chris Jeffers at 10:20am today. Jeffers had just spoke to the National Weather Service (NWS), who was eyeing the first strong cell to reach the Glendora area around 11:30am today.

According to Glendora city officials, they will remain at Yellow status in the Colby Fire Impact Area.

While one inch is nothing the Glendora hillsides can’t handle, if those stronger and unstable cells bring up to four inches on the burn areas it could become an issue. Four inches would increase the likelihood of going over the half inch per hour rain rate that is within the safety threshold for the bare hillsides.

GCN and city officials will continue to update residents as information becomes available from the NWS.

Below is video of yesterdays minor mudslides and debris flows which brought minimal problems to the Colby Fire Impact Area. By contrast, yesterday’s storm brought 2-5/8 inches of rain to the north part of our city.
