Good day everyone!

Thank you for all of your well wishes for my son.  His Asthma is doing better, since he was able to get more medicine.

I don’t know why, but we still have 98L designated as an INVEST.

Current satellite imagery indicate this system is still undergoing wind shear from the west.  Albeit an outflow channel is established to the north, noted in the imagery and in upper level wind analysis, winds through the deep layer are not conducive for further development, and the current wind shear forecast indicates upper level winds to remain non conducive during the next 4-5 days.

ATCF model track guidance has been discontinued.  Based on ATCF/FTP data from 12Z this morning, the disturbance is moving toward the NW.  Based on the current valid steering layers forecast maps, I expect this motion to continue for the next 48 -72 hours, before 98L re-curves into the westerlies.  I will continue to monitor this area for any significant changes during the next 72 hours.

Elsewhere, global models do not indicate any tropical development over the next 4-5 days, however the NCEP / EMC Multi Model and Ensemble model forecast is hinting at a 50-60% chance of development near the Panama area between days 5-10 in the forecast period from 06Z this morning.   The 12Z update has not posted as of yet, but I will be looking at that run for consistency.  I will be monitoring the area, as well as the GOMEX, as upper level winds become very favorable in the GOMEX in about 48 hours, and the area of the Western Caribbean beginning around 72-96 hours into the forecast period.

NCEP EMC MULTI MODEL AND ENSEMBLE FORECAST 120-240 HOURS

Although we are getting close toward the end of Oct., the areas mentioned are favored climatologically for development.  I cannot rule out development, as the MJO Multivariate Phase Index forecast shows the majority of the dynamic forecast guidance bringing the MJO back into Octants 8 and 1 over the next week, however the signal may only be weak, to moderate.  The OLR anomaly forecast indicates an upward motion phase, however I believe it is too strong in the intensity.

I am at a loss for words about this season’s inactivity, and strange behavior.  One would swear we were in an El Nino pattern (dry air, unseasonable amounts of wind shear, etc.).  What is also somewhat unusual for a neutral ENSO pattern, is the EPAC is ahead of the Atlantic Basin in terms of storm totals.  EPAC is currently at 16 while the Atlantic Basin is at 11.

Tropical Storm formation is not expected through the next 48-72 hours.

Have a blessed day!

About palmharborforecastcenter

I am a Tropical Forecast meteorologist, providing hurricane forecasts during the Atlantic Hurricane Season. 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, and extensive research on numerous meteorological topics such as the MJO, NAO, satellite imagery interpretation, etc. I have been forecasting Tropical Weather (Tropical Storms and Hurricanes) since 1996, with my main client being three different Coast Guard Commands.

    Thanks for all the updates…… I know Hurricane season isn’t over but it just kinda seems done to me. But, then I could be totally wrong.
