***Updated at 5:00 p.m. to include information from the Central Pacific Hurricane Center’s 5 p.m. update.***
A Flood Advisory is still posted for parts of the Big Island at this hour even as Hilda continues to weaken. The track continues to shift south and away from the islands which is good news considering even with the given track we are forecasted to get more rain than we’ve seen in quiet a while.
The remnant low is moving west-southwest near 14 mph and this motion is expected to continue through Friday night before dissipation on Saturday. Maximum sustained winds are at 30 mph with higher gusts.

Moisture surrounding tropical depression Hilda will continue to bring a chance of heavy thundershowers to the Big Island tonight and Friday. As Hilda moves away later Friday, showers will diminish.
Trades are expected to keep blowing through Saturday. A trough will pass near the islands late in the weekend and early next week. The trough will weaken our trades again, bringing another spell of uncomfortably warm and humid weather along with a chance of locally heavy mainly afternoon showers.
***Updated at 3:30 p.m. to include information from the National Weather Service.***

Hilda has been downgraded to a tropical depression, as of the Central Pacific Hurricane Center’s 11 a.m. storm advisory.
Located about 235 miles south of Hilo, Tropical Depression Hilda is now carrying depression-level wind speeds of 35 miles per hour, moving in a west-southwest direction.
Tropical Depression Hilda has picked up forward speed slightly since earlier Thursday advisories, but the increase to 12 mph was expected.
Forecasts predict that Tropical Depression Hilda will continue its weakening through Satuday as the storm continues to the south. As that occurs, a large area of moist air is forecast to bring showers over the islands. Heavy thundershowers are within the realm of possibility, according to the National Weather Service. Tropical Depression Hilda is expected to cause weakened trades that will leave the air feeling humid over the weekend.
Surf swells will continue to produce advisory level surf along east and southeast facing shores on the Big Island, as well as Maui.
A High Surf Advisory is in effect for East facing shore until 6 p.m. Thursday, while a Small Craft Advisory is currently in effect for windward coastal waters until 6 p.m. Friday. A Flash Flood Watch is also in effect until 6 a.m. Saturday.

The Central Pacific Hurricane Center reported that the storm has maintained its speed at 9 miles per hour and continues to inch along.
National Weather Service officials continue to forecast wet weather for the Big Island. Heavy showers will bring the potential for flash flooding throughout the Big Island into the weekend, with clearing expected around Saturday.
Stick with Big Island Now as we bring you the latest on Tropical Storm Hilda.
As of 5 a.m. Hilda was located about 210 miles southeast of Hilo, moving west at 9 miles per hour, an increase in forward speed from earlier advisories.
The Central Pacific Hurricane Center reports that the storm has weakened a bit with maximum sustained winds of 40 mph and is barely hanging onto its tropical storm status.
The system is expected to continue to weaken Thursday and into Friday and will become a tropical depression once it dips below 39 mph winds. That is expected to occur this afternoon.

Rainfall along the north portion of Tropical Storm Hilda is expected, as well as large swells that may produce high surf along east and southeast facing shores.
A High Surf Advisory is currently in effect for east facing shores on the Big Island. A Flash Flood Watch is expected to go into effect Thursday morning at 6 a.m. The Tropical Storm Warning for offshore waters from 40nm out to 240 nm has been reinstated.
Tropical storm force winds extend outward up to 60 miles. The moisture field reaches far beyond that and 4 to 8 inches of rain with isolated amounts up to 12 inches are still expected in some Big Island locations.

Hilda will pass far enough to the south of the Hawaiian Islands to avoid direct impacts but the associated moisture plume north through east of the system may trigger heavy rainfall, flash flooding and mudslides across portions of the Aloha State.
Moisture associated with Hilda will clear the state on Saturday. A trough passing near the islands later in the weekend will cause trade winds to weaken and shift out of the east-southeast into early next week.
