Tropical Storm Nolo will gradually accelerate westward away from the state over the next several days. Elevated moisture content being drawn up in the southeast flow will maintain a wetter pattern for Hawaii through the end of the week. Then drier trades are expected to return over the weekend.
Moderate to breezy southeast winds will gradually ease tonight into Thursday as Tropical Storm Nolo tracks west, away from the state. Outer rain bands associated with Nolo will bring showers mainly over Kauai and Oahu from the south through Thursday, with Kauai expecting the most coverage. MVFR and even IFR conditions will be possible within these showers.
AIRMET Sierra for mountain obscuration above 2000 feet is in effect for all portions of the smaller islands due to clouds and showers moving in from the south and southeast. This AIRMET will likely continue through tonight, and likely through the day Thursday for Kauai and Oahu.

Moderate to fresh south to southeast winds will weaken slightly to moderate levels by Thursday as Tropical Storm Nolo slowly drifts westward away from the main Hawaiian Islands. Since winds and seas have decreased below advisory levels this afternoon, the Small Craft Advisory that was previously in effect for waters surrounding Kauai has been cancelled. East to northeast trades will fill back in across the waters this weekend.
The moderate, short to medium period west to southwest swell originating from Nolo will continue for Niihau and Kauai through Friday night. Additionally, a small background south swell continues for other islands. The next small, long period south swell energy will arrive either late Sunday or Monday.
Surf along other shores will remain small until moderate trades return late this weekend, providing a slight boost to east facing shores. Multiple rounds of tiny northwest swell energy will reach north and west facing shores this weekend into early next week as the storms tracking near the Aleutian Islands become increasingly active.
None.
