Flash Flood Watch
Tropical air has infiltrated the Ohio, Big Sandy and Kanawha Valleys raising the ante for flooding across the region.
Since the moist atmosphere is likely to remain in control for many days, the sequence of flooding events will take on three stages.
The first stage involves a thunderstorm dropping heavy rains and flooding streets as storm drains back up. That’s more of a nuisance.
The second stage involves multiple thunderstorms hitting the same area hard in say a 12-24 hour period, like we saw in Spencer WV just 2 weeks ago. That would spell city and county flooding with homes threatened and roads closed.
The final stage will lead to a serious rise on rivers with likely high water for Independence week activities. The Greenbrier, Ohio and Kanawha are but a few rivers that may be off limits to recreation next week.
The intensity, track and longevity of individual thunderstorms will go a long way to determining which areas will experience the worst flooding.
Add it up and the first of several Flood Watches has been issued by the hydrologists at the National Weather Service for our region.
My blog at wsaz.com talks about how this tropical air mass in time will have its origin in Central even South America!
One final note, Wednesday night's cells will be armed with strong winds and vivid lightning strikes. So local power outs are likely almost a year to the date of the 2013 Derecho.
