Flooding in low-lying spots is likely this evening as high astronomical tides are forecasted. A Coastal Flood Advisory will be in effect from 6 PM to 11 PM. Time of high tide is 8:41 PM.

TheDigitel.com has also produced a user-editable Google map of flood zones — if you find anything that’s not marked here, feel free to add it.
Thankfully, rain is unlikely to exacerbate the situation (though a popup thunderstorm can never be completely ruled out in the summer months). There’s activity west of here but it’s not currently forecasted to make trouble for us in Charleston. If that changes, we’ll tweet at @chswx.
Updated to indicate that the Coastal Flood Watch was replaced by the Coastal Flood Advisory, and to note the expiration time of the advisory.
