Predictions for 
2019 Hurricane Season


We've already provided you with Colorado State University's April Prediction for the Atlantic Basin.  NOAA has just released its predictions for the Atlantic Basin, Central and East Pacific regions.



Looking Back and Looking Ahead
Hurricane Season Approaching 

Looking Back at 2018

The 2018 Atlantic hurricane season  was the third in a consecutive series of above-average and damaging hurricane seasons, featuring 17 named storms, 10 hurricanes and 6 major hurricanes. The season will be best remembered for Hurricanes Florence and Michael, which caused significant damage in the Southeastern United States. 2018 was the first season since 2008 to feature four named storms active simultaneously (Florence, Helene, Isaac, and Joyce). The season also was the first on record to see seven storms that were subtropical at some point in their lifetimes (Alberto, Chris, Debby, Ernesto, Joyce, Leslie, and Oscar).

In the chart below, the numbers in parenthesis are the averages, so you can easily see that the 2018 Atlantic Hurricane Season was well above average.  For more details, read  NOAA: Destructive 2018 Atlantic hurricane season draws to an end.

Forecasters predict a 40% chance of a near-normal season, a 30% chance of an above-normal season and a 30% chance of a below-normal season for the upcoming hurricane season, which extends from June 1 to November 30.

NOAA’s forecasters predict a 70-percent likelihood of 9 to 15 named storms (winds of 39 mph or higher), of which 4 to 8 could become hurricanes (winds of 74 mph or higher), including 2 to 4 major hurricanes (category 3, 4 or 5; with winds of 111 mph or higher). An average hurricane season produces 12 named storms, of which 6 become hurricanes, including 3 major hurricanes.

East Pacific

An 80 percent chance of a near- or above-normal season is predicted for both the eastern and central Pacific regions. The eastern Pacific outlook calls for a 70-percent probability of 14 to 20 named storms, of which 7 to 12 are expected to become hurricanes, including 3 to 7 major hurricanes.

Central Pacific

The central Pacific outlook calls for a 70-percent probability of 5 to 8 tropical cyclones, which includes tropical depressions, tropical storms and hurricanes.

An important measure of the total overall seasonal activity is the NOAA Accumulated Cyclone Energy (ACE) index, which accounts for the intensity and duration of named storms and hurricanes during the season.  According to NOAA’s hurricane season classifications, an ACE value above 117% of the 1950-2000 median reflects an above-normal season. An ACE value above 175% of the median reflects an exceptionally active (or hyperactive) season.

Hurricane Season Dates 

Hurricane season in the Atlantic begins June 1st and ends November 30th. The Eastern Pacific hurricane season begins May 15th and also ends November 30th.

Hurricane Season Approaching 

Looking Back at 2017

The 2017 Atlantic hurricane season was a hyperactive and catastrophic hurricane season, featuring 17 named storms, 10 hurricanes and 6 major hurricanes – ranking it alongside 1936 as the fifth-most active season since records began in 1851. The season also featured both the highest total accumulated cyclone energy (ACE) and the highest number of major hurricanes since 2005.

In the chart below, the numbers in parenthesis are the averages, so you can easily see that the 2017 Atlantic Hurricane Season was well above average.  For more details, read  NOAA: Extremely active 2017 Atlantic hurricane season finally ends

Atlantic Hurricane Outlook & Seasonal Climate Summary Archive


The 2017 Pacific hurricane season was a moderately active Pacific hurricane season, featuring eighteen named storms, nine hurricanes, and four major hurricanes, though the season was significantly less active than the previous three seasons. The season saw near-average activity in terms of ACE, in stark contrast to the extremely active seasons in 2014, 2015, and 2016; and for the first time since 2012, no tropical cyclones formed in the Central Pacific basin. However, for the third year in a row, the season featured above-average activity in July, with the ACE value being the fifth highest for the month.

Patricia Strongest Hurricane Recorded Impacts Cruises & Ports

Other images: 5-Day track off – 3-Day track off 


Hurricane Patricia
UPDATE: OCT 24

Hurricane Patricia made landfall at the speed of 165 MPH and then quickly began to weaken.  Early reports indicated that it would not be as catastrophic as predicted, fortunately.   We have gotten word that AM Resorts and the airport in Puerto Vallarta has reopened for example, so that is very good news.   

Emergency Message for U.S. Citizens: Hurricane Patricia Dated: October 24, 2015

~~~~~~~~

The largest hurricane to ever assault the Western Hemisphere headed toward Mexico’s southwest Pacific coast on Friday with 200 MPH winds. Patricia was expected to make landfall by early evening, according to Mexico’s national weather service, with the eye passing along the small beach towns of Playa Perula and Playa Chamela, both in the state of Jalisco. The government of Mexico declared a state of emergency in dozens of municipalities in the states of Colima, Nayarit and Jalisco.

Hurricane Patricia is expected to remain a Category 5 hurricane until landfall in southwestern Mexico in a few hours. After landfall, a combination of the mountainous terrain of Mexico and increasing shear should cause the cyclone to rapidly weaken, with the system likely to dissipate completely after 36 hours, if not sooner.

HAZARDS AFFECTING LAND

WIND:  Hurricane conditions should spread across the hurricane
warning area during the next few hours, with the worst conditions
occurring near where the eye of Patricia makes landfall.  Tropical
storm conditions are spreading across portions of the warning area.
Preparations to protect life and property should be rushed to
completion.  Hurricane conditions are possible in the hurricane
watch area this afternoon and this evening.

RAINFALL:  Patricia is expected to produce total rainfall
accumulations of 8 to 12 inches, with isolated maximum amounts of 20
inches, over the Mexican states of Nayarit, Jalisco, Colima,
Michoacan, and Guerrero through Saturday.  These rains could produce
life-threatening flash floods and mud slides.

STORM SURGE:  An extremely dangerous storm surge is expected to
produce significant coastal flooding near and to the right of where
the center makes landfall.  Near the coast, the surge will be
accompanied by large and destructive waves.

SURF:  Swells generated by Patricia are already affecting portions
of the southern coast of Mexico, and will spread northwestward
during the next day or so.  These swells are likely to cause
life-threatening surf and rip current conditions.  Please consult
products from your local weather office.
