Tropical Depression 19 Forms in the North Central Atlantic; No Threat to Land

Tropical Depression 19 forms over the open north central Atlantic Monday morning. As of 5 PM AST max sustained winds are at 35 mph as it slowly moves north-northeast well east of Bermuda. The depression is disorganized as it battles some nearby dry air in the mid levels of the atmosphere. Westerly wind shear exposes the center of circulation. Tropical Depression 19 will likely become the 17th named storm of the 2017 Atlantic season, Rina, by early Tuesday morning. While gradual strengthening is expected, it will transition to an extra-tropical system over the cooler north Atlantic by Thursday afternoon. It is no threat to land, but the remnants of future Rina could bring squalls to Ireland/the United Kingdom by Friday or Saturday.

30 Days Left In The Atlantic Hurricane Season

16 named storms, 10 hurricanes, 6 major hurricanes… It’s been a historic season in so many ways, and thankfully we’re starting to see the light at the end of the tunnel. Here’s a look at the storms we’ve seen through October.

Just 30 days remain in the 2017 Atlantic Hurricane Season and this is the time of year when activity starts to diminish rapidly. In fact, only 5% of named storms since 1950 have formed during the month of November. There are only 3 hurricane landfalls in the continental U.S. on record during the month of November. The most recent being Hurricane Kate (Cat. 2) that hit the Florida Panhandle on November 21, 1985.

In November, tropical systems usually form either in the WSW Caribbean or in the western Atlantic northeast of Cuba. In these areas, water temperatures are still warm enough for storms to thrive and wind shear is low. Closer to the United States there is some level of protection thanks to 1) rapidly cooling Gulf of Mexico waters and 2) more wind shear being present over the Gulf due to frequent cold fronts dropping south. Most November storms end up being more of a problem for places like Cuba, the Bahamas, and Bermuda.

All is quiet across the Atlantic right now, lets hope it stays that way for the next few weeks.
