News Summary
Tropical Storm Humberto is expected to strengthen into a hurricane by Saturday, while Invest 94L is developing over the Dominican Republic.

Residents are urged to stay informed as forecasts continue to evolve.
Charleston, South Carolina – Tropical Storm Humberto is forecasted to strengthen into a hurricane by Saturday, with predictions suggesting it may reach Category 2 hurricane status by next week. The storm’s projected path indicates that it will move northwest, potentially skirting near Bermuda during its progression.
Additionally, a tropical wave known as Invest 94L is being closely monitored, currently located over the Dominican Republic. This system is anticipated to develop into a tropical depression near the central and northwest Bahamas in the days ahead. Some forecast models indicate that Invest 94L could take a direct path impacting South Carolina, with potential effects reaching from Charleston to Columbia and possibly as far as the Greenville/Spartanburg area early next week.
The European forecast models have hinted that Invest 94L may strengthen into Tropical Storm Imelda, while the GFS (Global Forecast System) models present a possibility of it becoming a Category 1 hurricane. Current guidance shows a likelihood of “Imelda” forming within the next couple of days. The interaction between Humberto and Invest 94L complicates the forecast, especially given their proximity to one another.
Potential Impacts from Humberto and Invest 94L
The current steering patterns and forecast confidence are being regarded as low due to this dual-system scenario. Despite this uncertainty, some tropical moisture is likely to affect the Upstate South Carolina area. Anticipated impacts from the storms include wind threats and significant rainfall totals, especially from Monday to Tuesday of next week. Current model data is starting to align regarding the potential paths and developments of these two weather systems.
