A FLASH FLOOD WATCH REMAINS IN EFFECT FROM WEDNESDAY MORNING THROUGH THURSDAY MORNING.
The Flash Flood Watch continues for:
- A portion of central Pennsylvania, including the following areas, Adams, Bedford, Blair, Cambria, Clearfield, Columbia, Cumberland, Dauphin, Franklin, Fulton, Huntingdon, Juniata, Lancaster, Lebanon, Mifflin, Montour, Northern Centre, Northern Clinton, Northern Lycoming, Northumberland, Perry, Schuylkill, Snyder, Somerset, Southern Centre, Southern Clinton, Southern Lycoming, Sullivan, Union and York.
- From Wednesday morning through Thursday morning.
- Heavy rainfall associated with Ida will result in an increased risk of flooding. Widespread rainfall totals of 3 to 5 inches are expected with locally higher amounts up to 7 inches possible across south-central Pennsylvania. As the remnants of hurricane Ida approach, perhaps there are a few things we can do to minimize damage and potential loss.
Living on Lake half-mile above sea level gives us immunity to the type of massive flooding seen in New Orleans and other low-lying areas. It does not however make us any less susceptible to flash flooding due to long periods of intense rainfall particularly on the upstream side of flow restrictions such as culverts, bridges, streams, ditches and drainage pipes, as well as accumulated debris, downed trees, etc.
While we are not at all expected to see anything like our worst case flooding, of biblical proportions, a much more likely '50- or 100-year' storm could cause the lake itself to rise up to 2 to 3 feet above normal spillway level. It has happened before. Such a rise, should it occur again,or worse, could cause damage to boats and docks, particularly floating docks or craft which are attached rigidly or without sufficient slack to accommodate such a rise. Additionally small craft and accessories on the ground and not tethered could be blown or washed adrift, causing harm.
Please stay safe and vigilant. Take care.
