Tropical Update: 26 Mar

#1 Postby senorpepr » Fri Mar 26, 2004 2:19 pm

The only new addition today is the introduction of our first known hurricane in the South Atlantic Ocean: 01L.

:rarrow: A) TC Fay (18S): at 26/1613Z...
Position near 18.9S 120.0E (130nm NE of Port Hedland, Australia)
Movement toward the SW at 5 mph
Maximum sustained winds are 105 mph
Minimum central pressure is 949 mb
T# numbers: 6.0/6.0

Fay has gone through a reintensification phase as she is posed to bear down on the Australian Coast. Expect weakening throughout the period as Fay makes landfall.

:rarrow: B) TC Oscar (20S): at 26/1700Z...
Position near 17.5S 92.1E (410nm SSW of Cocos Islands)
Movement toward the SSW at 5 mph
Maximum sustained winds are 120 mph
Minimum central pressure is 938 mb
T# numbers: 4.5/5.5

Expect continued strengthening out of Oscar with open water downstream of him. The forecast has a 140 mph cyclone at the end of the period.

:rarrow: C) Ex-TC 21-S (21S): at 26/1700Z...
Position near 9.6S 53.5E (700nm NE of Antananarivo, Madagascar)
Maximum sustained winds are 25 mph
Minimum central pressure is 1004 mb
Potential for development: Fair

The remnants of 21S have become disorganized due to strong westerlies aloft. However, with good divergence nearby 21S, this system still has the potential for redevelopment.

:rarrow: D) Unnamed Hurricane (01L): at 26/1639Z...
Position near 29.0S 44.0W
Maximum sustained winds are 85 mph*
Minimum central pressure is 979 mb*
T# numbers: 4.5/4.5
(*Estimated from Dvorak Technique)

01L has been a system many have been watching over the past couple of days. Now, with the media attention, this has become quite the system. It’s very rare for cyclones to occur in the South Atlantic. Since the satellite era, this is the first hurricane to form in this region of the world. Not a lot of data is available on this system yet. NRL Monterey has it listed as Invest 01L. The Instituto Nacional de Meteolorogia out of Brazil hasn’t reported anything on it… as far as I have seen. I have, however, seen weather advisories for strong winds, probably associated with 01L for the state of São Paulo to the coast of Santa Catarina. We’ll see if the NHC issues any advisories on it. Regardless, this is something to watch. 01L is located off the Brazilian coast, a few hundred miles south of Rio de Janeiro.

Please utilize the above links for the latest advisories. For latest forecast tracks and satellite imagery (when available), go to the NRL Monterey's website at: http://www.nrlmry.navy.mil/tc_pages/tc_home.html

Remember for the latest storm information, to include watches, warnings, and storm track, please monitor products issued by your local weather office.

92S was added, but Oscar, IMO, is weakening.

I've been meaning to add 92S to the list, but 01L has kept me occupied.
