HAWAIIAN WEATHER -- ....

A TIMELY REMINDER -- Daylight Saving Time will go into effect this coming Sunday morning for essentially the entire nation -- the exceptions include Arizona, Hawaii, Puerto Rico and the eastern time zone sections of Indiana. These changes have been mandated by the U.S. Congress. In other words, following the old adage of "spring ahead, fall behind", you will need to turn your clocks ahead by one hour to conform with the local time observance.

What does this time change mean to you (other than later sunsets)? Contrary to a popular belief that has surfaced at times, the change from Standard to Daylight Saving Time does not add an extra hour of daylight to the day nor does it affect weather patterns. While the weather will not change because of the time change, the times when you will be able to obtain weather charts will now be one hour later. The reason is that the National Weather Service operates on "Z time" (variously called Greenwich Mean Time or Universal Coordinated Time) which does not observe Daylight Saving Time, and the charts are still produced and transmitted at the same Z time.
