Monday Morning Update

Hilda slowly strengthening

Hilda continues on a methodical, slow strengthening trend. At this rate, it may become a hurricane in the next 24 hours. At this time Hilda is expected to stay 250-300 miles south of the Big Island. It's possible that some rain bands could affect Hawaii by Wednesday. The strongest effects should stay south. Look for surf to pick up on the south / east facing shores over the next several days.

As of 8:00 am edt / 5:00 am pdt / 2:00 am hst tropical storm Hilda was centered near 14.3° N / 144.6° or about 785 miles east southeast of Hilo, HI. Top sustained winds are estimated at 65 mph (CPHC also estimates 65 mph). It is moving west at about 12 mph.

This system is NOT a threat to Mexico.

Monday Evening Update

Hilda essentially same strength

Hilda has fought some wind shear over the past several hours. Overall, the strength has not changed much, neither has the forecast which keeps Hilda south of the Hawaiian Islands as a minimal hurricane. Some rain bands may affect the Big Island as Hilda passes to the south. Swell will be higher than normal on the southern and east facing beaches.

As of 8:00 pm edt / 5:00 pm pdt / 2:00 pm hst tropical storm Hilda was centered near 14.9° N / 146.8° or about 640 miles east southeast of Hilo, HI. Top sustained winds are estimated at 65 mph (CPHC also estimates 65 mph). It is moving west at about 10 mph.

This system is NOT a threat to Mexico.

Tuesday Late Afternoon Update

Hilda is sick

Tropical storm Hilda is in sorry shape. It appears that wind shear has seperated the low level center from the mid level. Convection is weakening and is only on the south side of the mid level circulation.

As of 4:00 pm edt / 1:00 pm pdt / 10:00 am hst tropical storm Hilda was centered near 15.0° N / 150.0° or about 450 miles southeast of the Big Island, HI. Top sustained winds are estimated at 40 mph (CPHC estimates 50 mph). Hilda is moving west at about 10 mph.

Wednesday Morning Update

Hilda makes a comeback

Although the exact center is difficult to pinpoint, it appears to be again embedded under the mass of deep convection. Some showers from Hilda may brush the Big Island as Hilda passes to the south.

Wind shear has done Hilda in. It is currently poorly organized well south of the Hawaiian islands. Unless there is a reformation of Hilda, this will be our last update.
