One-week forecast for each prefecture is issued at 11:00 and 17:00 JST every day. Latest daily forecast is displayed in the columns of the first and second day. Probability of Precipitation for today and tomorrow is displayed with six hours as a unit (i.e. 00-06/06-12/12-18/18-24 JST).
Figures shown in parentheses in the rows of Low and High temperature indicate the ranges of error in degrees Celsius. The reliability of the day is represented as A, B or C, in descending order of expected accuracy; in 2007, accuracy of precipitation forecast on average was 86% for A and 56% for C.
Values in the column of normal precipitation represent the range of normal precipitation amount accumulated in the period of coming seven days, while normal low/high temperature represents those in the fourth day of the period.
