At 3:27 p.m. Doppler Radar indicated a thunderstorm producing heavy rain over the Fort Pearce Wash n Arizona.

Precautionary / Preparedness actions:

Move to higher ground now. Act quickly to protect your life.

“Get everybody. Don’t try to save personal belongings or vehicles,” Deputy Darrell Cashin, Search and Rescue Commander with the Washington County Sheriff’s Office, said as a watchword for those confronting a flash flood.

A flash flood can happen with little or no warning and individuals may only have seconds to act before it’s too late.

After getting to higher ground, it is important for individuals to remain where they are until either the waters have receded to a safe depth or rescue has arrived.

When you think it’s safe, wait an hour longer

“Let it recede, let it pass,” Cashin said. “When you think it’s safe, wait an hour longer.”

Turn around, don’t drown

    20140818.1837 Fort Pearce Wash expected to rise by eight feet in next one hour. Trails being closed. Golf course and auto row expected to see some flooding. Should be interesting.

      We have a reporter at Tonaquint and Southgate – Hilton Drive – bone dry at 7:25 p.m. That doesn’t mean a flood won’t flash though.
      Thanks, jmb

    Reminding me of some of the storms we got back in Georgia. I admit it, I was sitting on the sofa and then bam it scared the crap out of me. Almost like tornado weather. Its the worst I have seen since we moved here.
