NYC Area Forecast: Unsettled weather continues as Florence stays south

/0 Comments/by

Good morning! Over the next few days, a large upper-level ridge will be building into the area from the Western Atlantic Ocean. Ridges like this would typically support the return of hot and humid conditions, but the area is sandwiched between high pressure to the north and Hurricane Florence off the Southeast US coast. As a result, an onshore flow has persisted and a frontal boundary has lingered over the region. This has lead to unsettled and muggy weather, which will continue into the weekend before high pressure takes over.

Florence may not make landfall in North Carolina. Does it matter?

/1 Comment/by

More than seven days after meteorologists first started tracking what would become Hurricane Florence, the weather pattern we have been advertising as “extremely unusual” finally threw another curveball at us. Forecast models over the past 24 hours have come into better agreement on the idea that Hurricane Florence will put on the brakes as she approaches the Carolina coast, coming to nearly a complete halt and turning southwesterly along the coast.

In fact, some models suggest that the storm may not even make an official landfall in North Carolina at all – instead, it will float southwestward toward South Carolina before weakening and moving inland. This has left the public with a lot of questions. What is going on? What does this mean, and should we believe it? Does this matter in terms of overall impacts? Does this new change in the track of Florence really matter for those in its path? The answers aren’t simple, but they are there – and forecast models have been giving us clues all along.

Extremely dangerous Hurricane Florence heads towards Carolinas

/0 Comments/by

Hurricane Florence weakened briefly this morning, but remains a powerful Category 4 hurricane with maximum sustained winds of 130 miles per hour. The weakening can mostly be attributed to an eyewall replacement cycle or “ERC”, which occurs when the inner eye-wall of a hurricane erodes in favor of a larger, more expansive one. The good news is the temporary weakening of the storm system. The bad news is the window for additional strengthening that occurs afterward.

To make matters worse, Florence is set to enter a nearly optimal environment for strengthening later today. Anomalously warm ocean temperatures, some of the warmest in the Atlantic Ocean, lie ahead of the storm. In addition, low mid level atmospheric shear will allow the storm to properly ventilate. After the eyewall replacement cycle is complete, Florence may additionally strengthen today, perhaps approaching Category 5 status.
