As the Lowcountry's weather turned tranquil Monday morning, forecasters continued to warn beachgoers to stay out of the ocean because of life-threatening rip currents.
It's the area's most significant weather phenomenon to look out for this week, according to the National Weather Service station for the Charleston area.
The rip currents were affecting the southern South Carolina and northern Georgia coastlines, according to a Weather Service statement.
"No one should enter the surf," the forecasters warned in the statement. A small craft advisory is in effect. The threat comes as Tropical Storm Cristobal spins just west of the Bahamas.
The storm, with sustained winds of 50 mph, was moving northward at 3 mph, according to the National Hurricane Center in Miami. It was expected to pick up speed and curve northeastward, far away from the U.S. mainland, and become a hurricane by midweek west of Bermuda.
All that activity offshore comes after a record high temperature of 99 degrees in Charleston and as the area experiences a brief fall-like respite from the hot weather.
The high temperatures this week are expected to creep back up toward 90 degrees, but forecasters anticipate little when it comes to rain.
They predicted only a 20 percent chance of rain Monday and Tuesday, but that chance will disappear, only to return again for the weekend.
Here is the complete forecast:
