MYRTLE BEACH, SC (WMBF) - A powerful coastal storm will develop off shore through the day Saturday bringing periods of heavy rain and winds along the coast.

Rain will continue non-stop through the mid afternoon before gradually tapering off to mist and drizzle by the late afternoon and evening. Some of the rain could be heavy at times from the morning through the mid afternoon. Rainfall totals by this evening will reach 1 to 1.5 inches for most areas.

With the clouds and rain in place, temperatures will climb very little through the day with inland areas stuck in the upper 40s. The Grand Strand will see temperatures struggle to reach the lower 50s.

Winds will turn gusty at times by Friday afternoon and evening with gusts as high as 25-30 mph late in the day especially near the coast.

The storm off shore will rapidly intensify through the day on Saturday resulting in more rain and stronger wind gusts. The very worst of the storm will impact the Outer Banks of North Carolina where severe coastal flooding and damaging winds will develop on Saturday and Sunday.

Across our area, winds will increase through the day and turn very gusty by Saturday afternoon and evening. Along the coast, wind gusts of 40 mph will be likely and may reach 45 mph right on the beaches. Wind Advisories may be issued for the area on Saturday.

Rain will be more off and on during Saturday, but will also be heavy at times. A few bands of heavy downpours will move across the region especially during the afternoon and evening.

Just off shore, winds will be howling at 50 to 70 mph. These high winds will push wave heights to 20 to 30 feet over the Gulf Stream and result in very dangerous marine conditions.

Along the beaches, wave heights will grow to 6 to 9 feet late in the day on Saturday. This will likely result in some beach erosion at times.

Very strong winds off shore will build wave heights to 20-30 feet over the Gulf Stream.
