STORM. 2.B OTHER INFORMATIONS: T=6.0, CI=6.0 HONDO SEEMS HAVING REACH ITS MAXIMUM OF INTENSITY YESTERDAY, HOWEVER IT ALWAYS SHOWS A WELL DEFINED EYE, BUT CONVECTION IS LESS COLD. HOWEVER THE SYSTEM HAS A RATHER SMALL SIZE (CF MICROWAVE IMAGERY) AND SHOULD THEN QUICKLY REACT TO MODIFICATIONS IN THE ENVIRONMENTAL CONDITIONS. HONDO IS LOCATED BETWEEN TWO COMPETING STEERING FLOWS; SUBTROPICAL HIGH PRESSURES IN THE SOUTHWEST AND EQUATORIAL UPPER LEVEL RIDGE THAT REMAINS THE DOMINANT STEERING FLOW. IT HAS TRACKED SLOWLY EASTWARDS DURING THE VERY LAST HOURS, BUT IS EXPECTED TO RESTART SOON SOUTHEASTWARDS.HONDO IS THEN EXPECTED TO KEEP ON TRACKING SLOWLY SOUTHEASTWARDS, THEN QUICKER BEYOND 36 HOURS TOWARDS A WEAKNESS IN THE SUBTROPICAL RIDGE IN THE SOUTHEAST. WEAKENING IS EXPECTED TO BE STRONGER BEYOND 24 TO 36 HOURS ON COOLER SEA SURFACE TEMPERATURES.
