THESE STRONGER TRADES ARE EXPECTED TO CONTINUE THROUGH THE WEEKEND
AND THROUGH THE MIDDLE OF NEXT WEEK. A DISTURBANCE IN THE
TROPICAL EASTERLIES TO THE SOUTH OF THE SUBTROPICAL RIDGE INCREASES
MOISTURE SUNDAY AND MONDAY WHICH SHOULD INCREASE HEAVY RAIN

OTHERWISE, MAUKA SHOWERS ARE EXPECTED DURING THE NEXT WEEK.
