PLAN AND PREPARE

It’s one of our favorite days of the year in South Florida: Nov. 30 means we have officially made it to the end of the Atlantic hurricane season.

People who live near the coast in Miami-Dade and Broward counties will be in the mid-upper 50s, while those further inland will feel a chill in the mid to even low 50s.

It’s a sweater-weather type of morning, as Miami and Fort Lauderdale woke up to temperatures in the 50s on Wednesday.

Expect wind gusts to 35 mph along the coast. Heavy downpours will ride on the breeze, continuing this week's flooding threat into the weekend.

Heavy rain and severe thunderstorms caused power outages and flooded roads on Thursday evening in areas of Miami-Dade County.

A wintertime atmospheric pattern dominates the Atlantic, the Gulf of Mexico, and most of the Caribbean Sea. The jet stream has dipped far south over the U.S., which pushes cold fronts and dry air toward southern latitudes. No tropical systems can penetrate this type of weather pattern.

The non-tropical low-pressure system we’ve been following across the North Atlantic all week is likely down to its last day to get named. Either it quickly sheds its fronts – a legacy of its days as a coastal low off the Carolinas last weekend – or it gets absorbed by another big North Atlantic system that’s hot on its heels before it can get named.

The non-tropical system we were watching at the beginning of the week, then gave up on yesterday, is back in a big way. The system is producing hurricane force winds over similar North Atlantic waters that Wanda plowed last week.

The slight possibility that the non-tropical system that tried to organize off the Carolina coast would evolve into a tropical-type weather system has diminished.

A non-tropical low-pressure system off the Carolinas has a robust circulation. This is the storm that produced heavy rain, wind, and extremely high tides at the coast over the weekend.

Tropical Storm Wanda has officially died.

South Florida will be getting a taste of the coldest air of the season so far starting Saturday night. Temperatures are forecast to dip to the 50s by Sunday morning.

Flooding has made for some transportation nightmares Friday in South Florida, from Fort Lauderdale down to Miami.

Friday's low and its associated upper-level disturbance are going to produce heavy rain over parts of Florida today, but the energy for this storm is not coming from the Gulf water.

The coolest air of the season is on the way with low temperatures near 60 degrees Sunday and Monday morning. Some areas may even drop into the 50s.

Tropical Storm Wanda is caught in an area of weak steering flow in the middle of the Atlantic. It’s drifting north and is forecast to drift back south again over the next couple of days before a strong enough dip in the jet stream comes along. That scoop should send it off into the North Atlantic.
