Rocky Times Thanks to Sandy

Sandy is onshore, but still a major risk. Tony documents her effects locally.


Sandy Strikes Jersey Coast, Triple Threat Locally
Early Monday evening Hurricane Sandy roared onshore in South Jersey not far from the casinos in Atlantic City. The highest wind gust I noted was 90 miles per hour with sustained winds in places of 50 miles per hour. That’s enough to generate power outs in the 2-4 million people range over an 8-10 state area.
The storm surge of rising waters on top of a high astronomical tide a big story in Jersey, New York and New England.
For our region, the effects from Sandy while “muted” will still be substantial. It is a rare triple threat from a hurricane here at home.
The main risk for power outs overnight will come from strong winds locally. Displaced from Sandy by 300-500 miles our region will experience the strongest winds from 2 in the morning until 2 in the afternoon Tuesday. I expect most areas will see winds sustained at 25 mile per hour with gusts to 45-50.
Halloween inflatables and candidate signs that are fragile will prove no match for the “mighty” gusts.
To put these winds in perspective, during the derecho of June 29th, most areas experienced winds for a half hour sustained at 30 and gusting to 60 miles per hour. Momentary gusts mustered an 80 mile per hour might.
Since we are coming off a dry October, the ground is relatively firm even after rains of the past 2 days. That means power outs will be more scattered at first light of day.
So far the 2 day rain total is generally an inch to 2, enough to bring some small streams up, but nothing close to flood stage. Given the rains expected the next 24 hours, I would expect many small streams to rise to ¾ bankfull on Tuesday.
My concern for the Ohio River is a major rise by the end of the week when all Sandy’s rain water and melted snows work their way into the mighty river. I will watch the latest hydrographs from the NWS to help determine where a risk for high water exists.
As for the wet snows, they fell steadily all day Monday and Monday night in the West Virginia high country. By mid evening, Snowshoe had measured 8” at an elevation of 4848’ and Richwood near the 3,000’ level had 4 inches. Did I forget to mention it was still snowing and was expected to snow another 24 hours in those areas?
Given the relentless wind that will blow in the mountains through Tuesday, the NWS continues a Blizzard Warnings for most of mountainous WV. Accumulations of 1 to 2 feet will be common with Snowshoe and Canaan Valley likely to exceed that!
In the river valley towns of the Ohio, Big Sandy and Kanawha Valley wet snow should slush up the morning hours on Tuesday before melting away in rains on Tuesday afternoon. The hills around the valley towns climb another 500-1000 feet in spots which spells a slushy 3 inches of sloppy snow before the melt-off.
