This will be the Tropical Storm Grace, the 7th system of the Atlantic hurricane season 2021. The Atlantic generated no named storms in August, but three hurricanes roamed the basin in November. Followed by a secondary boost in the activity happening through mid-October. In early March, NOAAs Climate Prediction Center (CPC) declared an end to the triple-dip La Nia that was in place through the past three hurricane seasons. Sustained tropical-storm-force winds of 40 mph or greater are likely to reach the Florida east coast as early as Wednesday night. Copyright 2023 Nexstar Media Inc. All rights reserved. The National Hurricane Center's Tropical Cyclone Reports contain comprehensive information on each tropical cyclone, including synoptic history, meteorological statistics, casualties and damages, and the post-analysis best track (six-hourly positions and intensities). It is the first season to have at least five systems made landfall in Mexico, the most since 2018. Despite the record 2020 season, there isn't necessarily a strong correlation between the number of storms or hurricanes and U.S. landfalls in any given season. A leading Atlantic forecast calls for 17 named storms, eight hurricanes and four major hurricanes in 2021. Accumulated cyclone energy (ACE) is a way to measure a tropical cyclones intensity as well as its longevity. In other words, a season can deliver many storms but have little impact, or deliver few storms and have one or more hitting the U.S. coast with major impact. Despite the high number of storms that year, no hurricanes and only one tropical storm made landfall in the U.S. Even if water temperatures are warm and there is little wind shear, dry air can still disrupt developing tropical cyclones and even prohibit their birth.

According to the NHC, swells from Henri could reach much of the east coast of the U.S. and Atlantic Canada by the end of the week and continue through the weekend. They add that there is some risk of direct impacts from Henri in portions of the northeastern U.S. and Atlantic Canada. However, forecasters warn that uncertainty in the track forecast is larger than usual.
