East Fork Rose 11 Feet Today; Almost Out of Banks at FM1485

The East Fork of the San Jacinto at FM1485 received almost 10 inches of rain today, including almost two inches in one hour late this afternoon.

Just upstream at 2090, the East Fork also received more than 10 inches in heavy bursts throughout the day.

As a consequence, the East Fork has risen 11 feet in the last 20 hours. It currently stands at about 57 feet. Flooding becomes likely at 60 feet.

Therefore, the river has three more feet to rise before coming out of its banks at FM1485.
