Could the Atlantic's Next Named Storm Ruin Your July 4 Beach Plans?

The National Hurricane Center (NHC) has designated a zone off the southeastern coastline as being ripe for tropical development. What are the chances that this corner of the Atlantic births the next named storm of the season? Read on for all of the details of this emerging threat.

Area of Concern Developing Off the Coast of the Southeast

The NHC is monitoring an area of the southwestern Atlantic for potential tropical development in the days ahead. As of the Tuesday morning update from the nation's tropical weather experts, a cluster of rain showers and thunderstorms could pair with a large area of low pressure predicted to form in the next day or two. The formation of this area of low pressure along a stalled frontal boundary could provide favorable conditions for tropical development.

The chances of this feature taking on formal characteristics are still low at this point. According to the NHC, the area of activity has a 10% chance of formation through the next seven days. Like most tropical weather makers originating in the Atlantic, this potential system will move slowly to the west. Should a named storm come to life, it will go by the name Bertha. There has only been one other named feature to form in the Atlantic this early in the season. Conversely, the Eastern Pacific has been more active, with three named storms already on the books.

Forecasters note that there is still a great deal of uncertainty surrounding whether this system will take on defined tropical characteristics. However, even in the absence of formal development, the rain and winds associated with the area could translate to impacts to the Southeast and Florida this week. This is poor timing as the nation gears up to celebrate its 250th birthday with a variety of outdoor plans.

The emergence of a heat dome over the central and eastern U.S. will also send more people to the beach seeking relief from the steamy conditions. Beachgoers will want to be aware of the possibility of dangerous rip currents and large waves produced by the system brewing out to sea.

Where to Expect Rain and Storms This Week

Scattered rain showers and thunderstorms are likely to pop up across the Southeast and Florida as the system lurks offshore this week. You can expect about 2 to 3 inches of rain over the next several days. While this is not an exceptional amount of rain compared to typical totals for this region, any little bit of moisture will help to improve the ongoing drought conditions across the Carolinas and in Florida.

Beachgoers heading out to Myrtle Beach, South Carolina, will enjoy mostly dry conditions in the days leading up to the holiday. However, this could change on the Fourth of July when the threat of storms enters the picture. It will be a steamy stretch of days with readings in the upper 80s and high humidity levels amplifying the heat. The greatest chance of rain and storms will come on Sunday along this area of the coastline.

The risk of rain and storms ruining outdoor festivities surrounding the holiday will arrive earlier in Florida. Jacksonville should be ready for storms to pop off on Friday. This threat will persist into the holiday, making it important to stay on top of the hourly forecast.

As it stands now, the greatest threat to emerge out of this pattern is likely to be the risk of rough seas and rip currents. Be sure to check any posted warnings before heading into the water this week.

This is the time of the year when it is more common for tropical weather events to erupt right off the coastline. Known as homegrown systems, these early-season storms tend to form as fronts move through the region. Fronts moving from west to east across the U.S. often stall out when they reach the warm ocean waters of the Atlantic. This stalling pattern encourages the development of rotation along the boundary, providing the impetus for tropical weather to ignite if the necessary atmospheric conditions are present.

Climatologists have been warning that the recent emergence of El Niño makes it more likely that tropical weather systems will form closer to home. This is especially true during the early part of the season, before tropical waves begin coming off the coast of Africa with more frequency.
