For the remainder of the season, we expect an additional 8-15 named storms, with 4-8 becoming hurricanes and 2-4 of those becoming major hurricanes.

Another contributing climate factor this year is the possibility of La Nina developing in the months ahead. The ACE index measures the combined intensity and duration of all tropical storms and hurricanes during the season. Stronger and/or longer-lasting impacts could result in activity near the lower end of the predicted ranges, while weaker and/or shorter-lasting impacts could favor activity near the upper end of the predicted ranges.

The average of the dynamical model predictions for the Niño 3.4 region indicates ENSO-neutral through the remainder of the year, while the average of the statistical models predicts a weak El Niño.

Current conditions and model forecasts still point to competing factors during at least a portion of the ASO period. However, because El Niño has now dissipated, the suppressing factors are now expected to be weaker and of shorter duration compared to the May outlook, thus increasing the likelihood of a more active hurricane season. There are no tropical cyclones in the Atlantic at this time. 2021 Atlantic Shark Fishery Year Quotas, Opening Dates, and Retention Limits. Polar DMSP/AMSU Imagery. Today, the agency released its annual August update to the Atlantic Hurricane Season Outlook, initially issued in May. There is about a 50% chance of La Niña during August-October, and virtually no chance that El Niño will develop and suppress the hurricane activity this season. a. ENSO-neutral (i.e., No El Niño or La Niña) is most likely during ASO 2019. The 2019 Atlantic hurricane season is predicted to produce (with 70% probability for each range) 10-17 named storms, of which 5-9 are expected to become hurricanes, and 2-4 of those are expected to become major hurricanes. J. These upper-level wind anomalies are situated along the southern flank of a persistent and amplified subtropical ridge at 200-hPa, as indicated by positive streamfunction anomalies extending from the Caribbean Sea across tropical northern Africa. The latest weekly Niño 3.4 index value was -0.8 °C, which exceeds CPCs lower threshold for La Niña. The outlook indicates an 85% chance of an above-normal season, only a 10% chance of a near-normal season, and a nominal 5% chance of a below-normal season.See NOAA definitions of above-, near-, and below-normal seasons. Chen, W. Y., and H. van den Dool, 2003: Sensitivity of Teleconnection Patterns to the Sign of Their Primary Action Center, Mon. For the remainder of the season, we expect (with 70% probability for each range) an additional 10-16 named storms, with 5-9 becoming hurricanes and 3-6 of those becoming major hurricanes. and disturbances with tropical cyclone formation potential over the next five days. US Dept of Commerce The For the MDR as a whole SSTs during July were about 0.2°C above average. The updated outlook calls for 19-25 named storms (winds of 39 mph or greater), of which 7-11 will become hurricanes (winds of 74 mph or greater), including 3-6 major hurricanes (winds of 111 mph or greater).

Current oceanic and atmospheric conditions that make an “extremely active” hurricane season possible are warmer-than-average sea surface temperatures in the tropical Atlantic Ocean and Caribbean Sea, reduced vertical wind shear, weaker tropical Atlantic trade winds and an enhanced west African monsoon. 3 ways satellites connect scientists with ocean life. as conditions warrant.

NHC issuing advisories for the Eastern Pacific on Hurricane Marie; Hurricane Warning: East Pacific High Seas Gale Warning: East Pacific High Seas NHC Director Ken Graham discusses the heart of the 2020 hurricane season

Four inter-related atmospheric features are now present in the eastern MDR and western Africa in association with the ongoing high-activity era, and they are expected to persist.

Also, all four models are predicting below-average vertical wind shear across the northern MDR extending northward across the subtropical North Atlantic. Glossary, Privacy Policy

According to NOAA's hurricane season classifications, an ACE value between 71.4% and 120% of the 1981-2010 median reflects a near-normal season.

nhcwebmaster@noaa.gov, Central Pacific Hurricane Center Presented at AMS 33rd Conference on Hurricanes and Tropical Meteorology, April 2018. This updated outlook indicates a 70% chance that the seasonal ACE range will be 85%-165% of the median.

The Atlantic hurricane region includes the North Atlantic Ocean, Caribbean Sea, and Gulf of Mexico.

An inter-related set of atmospheric and oceanic conditions, which is very conducive for hurricane development, is now present in the MDR and is expected to continue through the hurricane season.

The 2020 Atlantic hurricane season has already produced a May-July record of nine named storms, with seven tropical storms and two hurricanes.

Click here for the methodology used to calculate the daily NAO index. La Niña typically reduces the vertical wind shear over the Atlantic, thus also favoring a more active hurricane season.

J. As a result, it is not possible to reliably predict the number or intensity of landfalling storms in a seasonal outlook, or whether a given locality will be impacted by a hurricane this season.

Reasons why the likelihood of an above-normal season has increased. "NOAA has the most highly trained and dedicated forecasters that serve to protect American lives and property.

Climate, 21, 3929-3935.

Predicting these impacts is an ongoing scientific challenge facing climate scientists today.

NOAA will continue to provide the best possible science and service to communities across the Nation for the remainder of hurricane season to ensure public readiness and safety,” said U.S. Secretary of Commerce Wilbur Ross. This outlook is probabilistic, meaning the stated "likely" ranges of activity have a certain likelihood of occurring. To date, the 2019 Atlantic hurricane season has produced two named storms (one each in May and July), with one becoming Hurricane Barry.
