Even minor flooding can disrupt transportation and require sandbagging or other protective measures. Residents and local authorities in the affected counties should prepare for continued high water levels and potential seepage issues, especially in levee districts. The forecast for a gradual recession offers some relief, but the duration of the warning underscores the need for vigilance.
