[2000 Eastern Pacific Hurricane Season]

Hector formed southwest of Mexico, moved westward and dissipated over colder water southwest of Baja California. The remnants of Hector passed over the Hawaiian Islands several days later, producing heavy rain over most of the island chain.

a. Synoptic history

Hector developed from a tropical wave that moved off the African coast late on 29 July, accompanied by 24-h pressure falls of about 4.0 mb. The wave maintained little deep convection as it moved across the central Atlantic Ocean at about 15 knots. Convection increased when the wave interacted with an upper-level trough in the central Caribbean Sea on 4 August, but the upper-level winds remained unfavorable for tropical cyclone formation while the wave moved into Central America.

The tropical wave slowed and moved across Mexico, emerging into the eastern Pacific Ocean on 9 August. Deep convection increased significantly when the wave moved off the coast and cloud-banding features began to develop on the morning of 10 August. It is estimated that a tropical depression formed at 1800 UTC 10 August about 160 n mi southwest of Manzanillo, Mexico. The system developed under northeasterly shear. However, banding features became more distinct on the evening of 11 August and satellite estimates indicated that the depression had reached tropical storm status.

Hector slowly became more organized except the outflow which remained restricted in the northern semicircle. A strong ridge to the north steered the storm generally westward about 10 knots into a more favorable upper-level environment for strengthening. It developed a Central Dense Overcast and a "ragged eye" began to appear on visible satellite pictures. The storm became a hurricane at 0000 UTC 14 August and it is estimated that the hurricane peaked in intensity around 1200 UTC 14 August while crossing the 26 C sea surface temperature isotherm. Hector rapidly weakened after it took a brief northwest track into much cooler water and less favorable upper-level winds. Most of the deep convection associated with Hector had weakened by 1800 UTC 15 August. Hector dissipated the next day and its remnants moved westward. On 20 August, the remnants interacted with an upper-trough near the Hawaiian Islands producing locally heavy rain and some thunderstorms.

The best track is listed in Table 1 and is plotted in Fig. 1.

b. Meteorological statistics

Figure 2 and Figure 3 shows the best track curves and maximum sustained 1-min surface winds and minimum central pressure data, respectively, as functions of time. These plots include Dvorak satellite classification estimates and early pressure estimates from synoptic analyses. SSM/I and TRMM microwave data were included in the analyses. The storm's remnants produced locally heavy rainfall over the Hawaiian Islands.

c. Casualties and damages

No casualties or damages were associated with Hector.

d. Forecast and warning critique

The official average track forecast error for Hector ranged from 74 n mi at 24 hours to 183 n mi at 48 hours to 290 n mi at 72 hours (5 cases only). The error at 24 hours is near the most recent ten-year average error, while the forecast error at 48 and 72 hours is considerably above the average error. However, this average is over five cases only and might not be representative.
