ATL OMAR: Remnant Low - Discussion

[Epsilon_Fan]

looks like it's trying to pull an Epsilon, I wonder if it will loop around or become extratropical and go into the E. Atlantic

A Tropical Storm again per Best Track:

Hey you're biased!!!!!

Repeating the 1100 PM AST position...31.5 N...52.8 W. Movement
toward...northeast near 16 mph. Maximum sustained winds...65 mph.
Minimum central pressure...989 mb.

[Chacor]

CENTRAL CONVECTION...AND I USE THAT TERM QUITE LOOSELY IN THIS
CASE...HAS CONTINUED TO RAPIDLY DECREASE AND INNER-CORE CLOUD TOPS
ARE BARELY -20C...WITH MOST TOPS WARMER THAN -10C. ONE COULD
CERTAINLY ARGUE THAT OMAR MAY NOT EVEN BE A TROPICAL CYCLONE.



Very warm cloud tops indeed, but there still is that eye feature.

THE INITIAL INTENSITY ESTIMATE OF 50 KT IS BASED THE WELL-DEFINED
EYE-LIKE FEATURE AND A DVORAK CI NUMBER OF T3.0/45 KT FROM TAFB.

Adiós Omar.

It looks like a remnant low pressure system.

[RL3AO]

The final advisory of the 2008 AHS? We can hope.

[cycloneye]

Finnally the last advisory has been written at 11 AM EDT.

[CrazyC83]

I don't think the season is quite over...we still have a while to go through...

As for Omar, hope you had fun out there, NOT! Don't let the slam on you! See you in 2014! (if we get that far)

[CrazyC83]

It seems to be trying to refire convection - only a little bit now, but it is a bit better than before. Shear is decreasing (and low ahead of it), so I wouldn't completely rule out Omar regenerating...

[CrazyC83]

Has to be an error? Best track still has it as a tropical storm...

AL, 15, 2008101900, , BEST, 0, 339N, 497W, 35, 1000, TS, 34, NEQ

[RL3AO]

Considering they didn't issue an advisory at 3z, I'd say error.

And to further prove its an error.

[Ptarmigan]

Omar has disappeared.

TROPICAL WEATHER OUTLOOK
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
200 AM EDT SUN OCT 19 2008

FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

THE REMNANTS OF OMAR ARE CENTERED ABOUT 900 MILES EAST-NORTHEAST OF
BERMUDA. RE-DEVELOPMENT AS A TROPICAL CYCLONE IS NOT EXPECTED.

AN AREA OF DISTURBED WEATHER IS OVER THE NORTHWESTERN CARIBBEAN
SEA...ASSOCIATED WITH A BROAD AREA OF LOW PRESSURE. LITTLE MOTION
IS ANTICIPATED AND DEVELOPMENT...IF ANY...WILL BE SLOW TO OCCUR.
THIS SYSTEM WILL LIKELY PRODUCE CLOUDINESS AND HEAVY RAINS OVER
PORTIONS OF CENTRAL AMERICA...PRIMARILY OVER BELIZE AND THE EASTERN
YUCATAN PENINSULA OF MEXICO.

CLOUDINESS AND SHOWERS ASSOCIATED WITH A TROPICAL WAVE CENTERED
ABOUT 900 MILES WEST OF THE CAPE VERDE ISLANDS REMAIN DISORGANIZED.
UPPER-LEVEL WINDS ARE NOT CONDUCIVE FOR DEVELOPMENT AT THIS TIME.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
NEXT 48 HOURS.

[Matt-hurricanewatcher]

Just have to get a post on this system...

I feel this was a borderline cat4. I don't understand the 125 mph peak.

[HURAKAN]

AL, 15, 2008101606, , BEST, 0, 182N, 639W, 115, 958

Omar intensity up to 115 knots in the Best Track.

This season, 17 TD, 16 TS, 8 H, 5 MH { 1 Cat. 3, 4 Cat. 4, 0 Cat. 5 }
