Track of Maka

Tropical Depression Maka (01C), located approximately 370 nautical miles east-southeast of Wake Island, has tracked northwestward at 3 knots over the past six hours.

Animated multispectral imagery shows that convection has recently started to flare over the eastern half of the system.

Nevertheless, the system was downgraded to tropical depression strength due to a lack of convection over a fully-exposed low level circulation center (LLCC) and declining Dvorak estimates.

Maka is tracking northwestward along the southern periphery of a low- to mid-level subtropical ridge anchored around 30N 160E and should start to gradually reintensify as it moves further away from the tropical upper tropospheric trough (Tutt) cell and into an environment of more favorable (less than 30 knots) vertical wind shear. Maximum significant wave height is 18 feet.

Track of Felicia

Hurricane Felicia continues moving west toward the Hawaiian islands. At 1100pm HST the center of Hurricane Felicia was located about 675 miles East of Hilo Hawaii near 20.3°N 144.7°W.

The system is moving West or 280 degrees at 15 mph. Maximum sustained winds are near 80 mph. The hurricane is currently having no direct effect on weather around the Hawaiian islands.

Hurricane Felicia is forecast to weaken and continue west toward Maui county and the Big Island over the next few days. The forecast track brings Felicia near or over those islands on Monday. Although the system is expected to weaken to a tropical storm as it reaches the islands it will still be capable of producing torrential flooding rains very high surf and damaging winds.

It is too early to provide exact values for wind rainfall and surf at specific locations. People under the watch should begin preparing now. Listen for possible warnings and be ready to evacuate if necessary. Heed the advice of local officials.

In the vicinity of the state, broken areas of cumulus and stratocumulus clouds, moving west at 15 mph, have increased over the windward waters north and east of the main Hawaiian islands in the last six hours. These clouds become overcast about 150 miles east of Hilo and continue towards the western edge of hurricane Felicia.

Animations show isolated light showers over windward waters and along the cloud plumes over water to the west of the islands. Over land, cloud cover is sparse over Kauai, Oahu, Molokai and Lanai and is mainly concentrated over windward and Mauka areas.

The intense green and brown of Kauai and Niihau, two islands in the Hawaiian Island Chain, stand out against the deep navy blue of the Pacific Ocean.

Kauai is the oldest of the main Hawaiian Islands and the fourth largest in the archipelago, with an area of 552.3 sq mi. Known also as the “Garden Isle”, it lies 105 miles (170 kilometers) across the Kauai Channel, northwest of Oahu.

Of volcanic origin, the highest peak on this mountainous island is Kawaikini at 5243 ft. The second highest peak is Mount Waialeale near the center of the island, 5148 ft above sea level.

High annual rainfall has eroded deep valleys in the central mountains, carving out canyons with many scenic waterfalls.

Lying 17.5 miles (28 km) across the Kaulakahi Channel to the southwest of Kauai, is Niihau, the smallest of the inhabited Hawaiian Islands, with an area of 69.5 sqmi.

Known as the “Forbidden Isle”,  the island has been privately owned since 1864 and is generally off-limits to all but relatives and guests of the island’s owners. Niihau is also referred to as the “Mystery Island”, the “Distant Isle” and sometimes the “Forgotten Island”, as it is frequently omitted on tourist maps.
