I will reiterate, my forecasts are based on the available information at the time of analysis, and are only as accurate as the information analyzed and the solutions provided.

Good evening everyone!

The following changes are being made. The forecast center is still closed on Sunday, and will be closed on Saturday as well (unless there is a threat from a tropical system, or a severe weather threat of a SLIGHT risk or above).

Regarding Tropical Weather Outlook issuance and Tropical Storm / Hurricane forecasts versus Severe Weather forecasts, IF a tropical system becomes a threat to the Caribbean islands, Mexico or any portion of the U.S. or becomes a constant entity in the Atlantic, Caribbean, or Gulf during any forecast of severe weather, the tropical system will take precedence.  These may be lengthy, however I want to always give a full perspective on the tropics.

STORM W SEASONAL FORECAST
TOTAL NAMED STORMS: 10 – 13
TOTAL HURRICANES :        4 – 6
MAJOR HURRICANES:        1 – 3

AVERAGE HURRICANE SEASON:
TOTAL NAMED STORMS: 14
TOTAL HURRICANES:         7
MAJOR HURRICANES:        3

CSU (Dr. Phil Klotzbach) SEASONAL FORECAST
TOTAL NAMED STORMS: 13
TOTAL HURRICANES:         6

Based on the NHC 12Z Surface Analysis map, Tropical Waves were located near 35W, 48W and 76W longitude. Black lines represent the axis of a wave.

Based on analysis this afternoon, the ECMWF model continues to indicate lowering MSLP anomalies JUN. 04 – JUN.05 in the Gulf, while the GFS is indicating a CAT 1 hurricane in the Florida straits. The GFS has been indicating this for the past 2 -3 days, however given the results of my analysis below, I am not buying this solution at the moment.
ECMWF AND GFS 192 HOUR MSLP ANOMALIES FORECAST


Current SST’s are warm enough in the Caribbean, Gulf and Gulfstream to sustain development. The minimum SST for tropical development is 26.5C or 80F (79.7)
CURRENT SEA SURFACE TEMPERATURES

The ECMWF MJO and ACCESS-S2 phase space models forecast shows the MJO entering PHASE 8 by the end of the month, into the first week of June. Based on past research, the ACCESS-S2 is supposed to be fairly accurate with the MJO forecast. The JMA CHI200 anomalies forecast currently indicates upward motion (BLUE COLOR) in the Gulf through June 19, and the ECMWF ENS EXT from 28 May through 02 June. The ECMWF EPS maps had not updated. Upward motion from the MJO can be favorable for tropical development as it can promote divergence aloft.

The following Tropical Storm Density anomaly map indicates the impact of the MJO for tropical development in PHASE 8 and 1. The map is based on actual observations (orange and red) and indicates the most likely areas to experience development.

The ECMWF EPS cyclone probability indicating a low probability of development in the Gulf in about 8 days At the moment, I do not expect develop. Although mid level relative humidity is favorable, as well as precipitable water, wind shear is currently forecast to remain high and unfavorable in the Gulf. Even though the MJO will be in a favorable phase and providing some divergence in the atmosphere, it would have to progress slower than forecast in order to provide a reduction in wind shear. The ECMWF Cyclone Formation Probability has slowly been concentrating more on the EPAC, and now indicates a MEDIUM (40%) probability for development, and conditions in the forecast will be more favorable in that area.

I do not expect tropical storm formation during the next 5 – 7 days. I will continue to monitor the tropics for any significant changes

Have a blessed evening!

About West Central Florida Hurricane and Severe Weather Forecast Center

I am a Meteorologist, Hurricane Specialist and Severe Weather Specialist, providing hurricane forecasts during the Atlantic Hurricane Season, severe weather forecasts during and off season, as well as winter weather and coastal storm forecasts. I retired from the U.S. Coast Guard in July of 2001. Meteorology became my passion in high school, and I have continued my educational background in meteorology since 1996, when I undertook the study of Tropical Meteorology. While working toward my degree, I had to unexpectedly withdraw from college due to my oldest sons medical reasons. I do however, meet the educational criteria of the AMS to be recognized as a meteorologist. Studies include, but are not limited to the Navy Aerographers Mate course, Naval METOC meteorology course, Meteorology 2010 Sophomore level course while attending St. Petersburg College, Clearwater, FL., Basic Forecasting course for operational meteorologists from Rapid WX meteorology institute, a four month meteorological internship at FOX 13 News, and extensive research on numerous meteorological topics. I have been forecasting Tropical Weather (Tropical Storms and Hurricanes) since 1996, with my main clients at the time being three different Coast Guard Commands.
