FIRST ALERT WEATHER DAY: July 4th downpours and rip currents


MYRTLE BEACH, SC (WMBF) – The First Alert Weather Team has declared today, July 4th, as a First Alert Weather Day for the combination of numerous outdoor activities and an increased chance of downpours and storms along with a risk of rip currents along the Grand Strand beaches.

An area of low pressure in the upper levels of the atmosphere will drift from the offshore waters of the Atlantic to the coasts of Georgia and Florida today, as this happens, a surge of moisture will move in from the Atlantic Ocean during the day on Wednesday resulting in a good chance of showers and storms at times. These downpours will be hit and miss but will likely have impacts on some outdoor activities at times through the day.


The surge of moisture will arrive in the Grand Strand through the first half of the day. Early morning showers will develop off the coast and then likely move onshore from sunrise through mid to late morning. Then, an early developing sea breeze will lead to more downpours and a few storms at times through midday. By the afternoon and evening, most of the rainfall will push inland leaving just an isolated shower or storm possible for afternoon cookouts and evening fireworks.

Across the Pee Dee, the better chance of rain arrives in the afternoon. While a stray shower will be possible in the morning, the best chance of downpours and a few storms will arrive after midday as the sea breeze starts to push well inland. The early afternoon through early evening will feature the best chance of rain. By the evening hours and for most fireworks displays, the surge of moisture will be pushing into central South Carolina and away from the Pee Dee.


No severe weather is expected, but brief gusty winds, lightning and locally heavy rainfall will be possible.

The onshore winds will also lead to an increased risk of rip currents. Beach goers should only swim in areas where life guards are on duty and pay close attention to warning flags posted along the beaches. The same onshore winds may also result in an increased number of jellyfish along the beach.

With so many parades, cookouts, beach plans, and fireworks displays scheduled for the day, the First Alert Weather team is dedicated to providing the latest information on the storm chances today.
