There’s a system in the Atlantic and it’s chilly in South Florida. You are not dreaming

Are your hurricane supplies almost gone? You might want to stop munching away.

Hurricane season isn’t over until Nov. 30, and there’s some activity in the Atlantic again.

UPDATE: Tropical Storm Sebastien has formed in the Atlantic. Here’s what the forecast shows

Forecasters are watching a broad area of low pressure about 250 miles northeast of the northern Leeward Islands that is becoming better organized early Tuesday, according to the National Hurricane Center.

“The chance of tropical cyclone formation within 48 hours is high,” according to Tuesday’s 6 a.m. advisory.

Forecasters say the system has a 80 percent chance of developing into a tropical or subtropical depression later Tuesday or Wednesday as it moves northward over the Atlantic.

The system, which was producing 30 mph winds Monday, is expected to have gale-force level winds by Tuesday night or early Wednesday morning, according to the advisory.

But it’s expected to be short lived.

The system is forecast to run into — and merge — with a cold front after midweek, stopping it from having any additional developments.

It’s not expected to affect Florida or any other land. But, you know what will affect Florida?

The cold.

The chilly temperatures that have Floridians cowering and bundling up — gloves, sweaters and churro runs included — arrived over the weekend.

While South Florida was slightly warmer Monday, with highs near 80, another cool front moving in could have you shivering with lows in the 60s the rest of the week.

At least the upcoming weekend looks like a nice compromise, with highs near 80 and lows near 70.
