 NOTES:

(1)  Even though gales were forecast for this system, it was not
     classified as a tropical cyclone.  The definition of a TC employed by
     Fiji requires that gales be present in at least one quadrant but close
     to the center.  The warnings for this system indicated that gales 
     were at some distance from the center.

(2) Dvorak rating (T2.5) on Jan 15 implies winds of 35kt.

(3) System was classified as a tropical low with report wind gusts of 45 kts.

 ---  ARANI (90Q)          MAR 09 - MAR 21  989      45   ---    SAT (1)


 
 NOTES:
(1) This system was classified as a subtropical storm by the Brazilian 
    Navy and National Weather Service and assigned the name Arani at 
    1500 UTC on 15 March.  Some satellite agencies rendered tropical 
    'T' classifications for Arani, so it bordered on being a 
    tropical storm.
