The NWS alert noted that the normal atmospheric forces that organize stronger thunderstorms that lead to funnel clouds or tornadoes were not present Thursday, but on occasion a stronger updraft associated with a thunderstorm can interact with a preexisting weak circulation or swirling winds near the ground and cause the circulation to increase in intensity and form a funnel cloud or a weak tornado. This is likely the mechanism that caused this funnel cloud to form.

According to the NWS, additional funnel clouds were not likely but could not be ruled out if another stronger thunderstorm and updraft form.

Isolated thunderstorms were forecast to continue over southwest Washington and northwest Oregon through the afternoon and into the early evening.

The NWS advised people to use caution and take cover should any threatening weather approach.
