WILMINGTON, N.C. (WECT) -Happy Tuesday evening! Your First Alert Forecast rolls on with toasty late summer weather as a sunny high pressure ridge supports daily high temperatures deep in the 80s and lower 90s through Thursday. . Some mainland corners of the Cape Fear Region may even dig deeper into the 90s on occasion. Overnight lows will trend above average also, with upper 60s and lower 70s ahead of the front. Lower 80s & middle 60s are daytime & nighttime averages respectively for this point in September.

Fall will officially arrive with the autumnal equinox at 9:03 p.m. Thursday evening. With its arrival, a strong cold front should pass in close proximity. Days will be mild to warm behind this front; nights and mornings ought to take a decidedly crisper turn with 60s and even 50s along with a nice drop in humidity. Despite this sharp transition, odds for significant rainfall will stay low.

Tropical Storm Gaston formed in the north central Atlantic late Tuesday afternoon, and will bring heavy rains and gusty winds to parts of Portugal’s Azores Islands. Invest 98-L is located east off the South American coast but will move towards the Caribbean in the coming days. Longer term this storm could be a U.S. concern but it is too early to talk specifics. Meanwhile, major Hurricane Fiona is likely to track 400 or more miles off the Carolina Coast. Though Fiona will grow very large and strong by mid to late week, its track clearance should be sufficient to preclude any direct Cape Fear storm impacts. Indirectly, though, Fiona will generate a period of heavier surf and rip current activity starting midweek, so please be alert should you find yourself at the beach.
