Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 803 AM EDT Mon Sep 03 2018 Valid 00Z Tue Sep 04 2018 - 00Z Tue Sep 11 2018 Trades will be on the lighter side early this week. Mainly windward/mauka showers are expected today. During tonight and Tuesday, both the GFS and ECMWF have an increase in available precipitable water, so amounts and coverage of showers could increase. On Wednesday, the trend reverses with drier air forecast to move across the islands, so Wed and Thu look to have less shower coverage and light amounts. Then later in the week the Central Pacific Hurricane Center will track tropical cyclone Norman and its potential impacts on Hawaii. Please consult the latest information from the the National Hurricane Center on both Norman and Olivia. Petersen
