Periods of rain expected for weekend
PDT Staff Writer
Nearly everyone across the eastern U.S. is wondering what the remnant of Hurricane Isaac will have on their plans for the Labor Day weekend. An exclusive Portsmouth Daily Times interview with Steve Travis of AccuWeather, says those participating in River Days might want to bring along an umbrella, which they might need to use from time to time from today through Monday.
“It still remains up in the air as to how exactly Isaac will effect the region,” Travis said. “But models are coming into a little better agreement in terms of how the storm will track across land.”
Travis said the storm is expected to take a more northward track arriving into north-central Missouri, curving toward the east, bringing it right along the Ohio River from Saturday until some time on Monday evening.
One of the features of Isaac is the slow movement of the storm.
‘There are a couple of factors working against a really quick progression of the system,” Travis said. “One is the high pressure area that is currently bringing some pretty nice weather, and that high pressure area is going to work to suppress Isaac to the west. Isaac will eventually overcome that high, but it’s going to take a while to do so. So because of that, that high is going to keep pushing against it, pushing against it, and Isaac is going to keep pushing back. Eventually something’s gotta give. That something in this case will be high pressure. The system won’t be as strong by the time it gets to us this weekend. But at the same time, because it is moving so slowly, we will see a fair amount of rainfall over the entire weekend.”
Travis said widespread rainfall amounts usually bring one to two inches.
“The majority of the rainfall will arrive around sunrise Saturday (today), and the system won’t really depart until Monday afternoon,” Travis said. “I don’t think it will be an all day rain event, sunup to sundown, but what we’re going to see is more in the order of banding - seeing a band of showers come through, making it wet for a while. Then it dries out for a little bit. Then more showers come through. The system is going to be weakening as it moves eastward. But the problem is that it is not moving anywhere too quickly.”
