Mississippi casinos in Sally’s path closed as waters rise WKRG-TV · September 16, 2020 at 7:33 am After strengthening on Monday, Sally’s strength has plateaued for now thanks in part to dry air wrapping into the circulation overnight. The Category 1 storm is barely moving at all and is not expected to move much over the next 12 to 24 hours. This means there may not be a big change in weather conditions during that timeframe but instead very slow and very gradual change over a long period of time. Storm surge from Hurricane Sally flooded the parking deck and parking lot a the Palace Casino Resort in Biloxi. On Monday, the Mississippi Gaming Commission ordered all 12 coastal casinos to close until further notice. Sally is forecast to make landfall Wednesday, bringing life-threatening storm surge and 8-16 inches of rain, with 24 inches possible in some locations.
