1995 Pacific hurricane season

The first of several quiet years

1995 was the first below-average eastern Pacific season since 1979 and the start of a run of quiet years in the basin. Its count, taken from the current NHC best track, lists eleven tropical cyclones, ten named storms, seven hurricanes and three major hurricanes, against an average of 16 named storms. The site's archive counts 11 tropical storms because it also includes Colleen, a western Pacific-numbered system that held tropical-storm winds for about a day in mid-November near the date line, outside the named-storm list for storms east of 140°W. The archive's calendar year also opens on 8 January with a brief depression in the same far-western waters.

Accumulated cyclone energy in the site's calculation came to 100.4, close to the best-track figure of 100.2. Most of that energy came from three long-lived major hurricanes that never threatened land. The Central Pacific Hurricane Center's 1995 report covers a single system, Barbara, which crossed 140°W as a weakening tropical storm; no storm formed in the central Pacific that year.

Adolph and Barbara build over open water

The year started slowly. Tropical Depression One-E formed on 21 May about 350 n mi south of Manzanillo and faded within two days without naming. Adolph followed in mid-June, drifting north off southwestern Mexico over warm water with strong outflow. It became a hurricane by 0000 UTC on 17 June and reached 115 kt and 948 mb at 0600 UTC on 18 June, based entirely on satellite estimates. Mexico issued a tropical storm warning and hurricane watch from Punta Tejupan to Cabo Corrientes, then dropped them once Adolph turned northwest and weakened over cooler water.

Adolph's forecasts missed the strengthening. The NHC report blames reliance on the NMC Aviation Model, which wrongly showed strong upper-level westerlies over the cyclone, and records two 65 kt under-forecasts at 48 hours.

Barbara, the longest-lived storm of the year, grew from a weak African wave that reached the Pacific on 5 July. It became a hurricane on 9 July, rose to 115 kt, lost its eye, then deepened again to a peak of 120 kt and 940 mb near 14 July while moving west under a strong ridge. It weakened over cooler water and crossed into the central Pacific as a tropical storm on 16 July, where the CPHC tracked its decay under westerly shear ahead of an upper trough near Hawaii. NHC track errors for Barbara ran far below the 1988 to 1994 averages.

A late-July and August procession off Mexico

Cosme formed on 17 July about 350 n mi south-southeast of the tip of Baja California and briefly reached 65 kt before cooler water broke it down; it never affected land. Tropical Storms Dalila and Erick followed from African waves, each peaking at 55 kt over the open ocean. Easterly shear kept Dalila's deepest convection displaced from its center for much of its nine days.

Tropical Storm Gil formed about 100 n mi southeast of Acapulco on 20 August and moved west away from the coast, peaking at 55 kt and 993 mb on 24 August. The NHC received no reports of casualties or damage, though heavy rain fell in southern Mexico early in Gil's life.

Flossie and Henriette on the Baja coast

Flossie grew inside a broad, deep low that covered the eastern tropical Pacific in early August, and ships showed tropical-storm winds before satellite estimates did. It tracked northwest parallel to the coast for a week, peaked at 70 kt on 10 August and kept its center offshore, while gusty winds and heavy rain reached southwestern Mexico and southern Baja California. The NHC cited El Nuevo Herald reports of five deaths in Puerto Vallarta and Mazatlán and amateur radio reports of two drownings in Cabo San Lucas. Rain peaked at 9.72 inches at San Felipe, Los Cabos.

Henriette formed on 1 September and became a hurricane on 3 September, when the ship WLDF reported 70 kt sustained winds about 20 n mi from the center and satellite estimates still stood at 55 kt. It reached its 85 kt peak at 1200 UTC on 4 September as the northern eyewall moved over the southern tip of Baja California, and the NHC estimated landfall at 1500 UTC with the same 85 kt winds. Mexican officials reported heavy road damage from surge flooding in Baja California Sur, harm to agriculture and 800 people forced from their homes. The NHC recorded no deaths.

Hurricane Ismael and the Gulf of California fleet

Ismael formed on 12 September about 300 n mi south-southwest of Manzanillo and turned north toward a mid- to upper-level low over Baja California. It became a hurricane on 14 September, peaked at 70 kt and 983 mb, and sped up to 18 kt through the Gulf of California. It made landfall near Topolobampo, Sinaloa, around 0400 UTC on 15 September with estimated winds of 70 kt and a pressure of 988 mb, then dissipated over the Sierra Madre. Its moisture spread across the southwestern United States and on toward the mid-Atlantic states.

The NHC's report cites newspaper accounts of 105 deaths and several people missing, many of them aboard fishing boats caught by strong winds and high seas, which made Ismael the fifth deadliest eastern Pacific hurricane of the century in its limited records. The Associated Press reported about 5,000 homes destroyed and thousands homeless, with some of the worst damage in Topolobampo. A later toll gives at least 116 deaths in Mexico, including 57 fishermen on 52 wrecked boats and 59 people on the mainland, and $26 million in damage in 1995 dollars.

Most track models sent Ismael west or northwest, away from land. Only the GFDL model steadily forecast the northward turn, and forecasters trusted it little after earlier false northward calls. Missing soundings from Socorro, Empalme and Mazatlán, and none at all from the Baja peninsula, left the models poorly initialized. The official 24 to 48 hour track errors ran two to three times the 1988 to 1994 average. The World Meteorological Organization retired the name Ismael in 1996, and Ivo took its place from 2001.

Juliette, the year's strongest

Juliette traced back to an African wave that trailed Atlantic Hurricane Luis and struggled to develop in its outflow. It became Tropical Depression Eleven-E on 16 September a little over 250 n mi south of Manzanillo, a small storm with a core of deep convection only 50 to 100 n mi across. It intensified fast on 18 September, paused near 105 kt, then reached 130 kt and 930 mb at 1200 UTC on 20 September, the season's highest wind and lowest pressure.

Concentric eyewalls then formed, and the outer wall left a large eye about 70 n mi wide before it shrank and Juliette briefly restrengthened to 90 kt. A mid-level low turned the hurricane north toward Baja California on 23 September, prompting a precautionary tropical storm watch, but shear and cooler water stripped its convection by 25 September. It drifted and dissipated on 26 September without reaching land, and the NHC received no reports of casualties or damage.
