Hurricane Polo: latest Baja California Sur warnings, closures and shelters
Hurricane Polo made landfall just south of Las Barrancas, Baja California Sur, around 0600 UTC September 29. The National Hurricane Center estimated Category 2 strength at landfall and forecast a second hurricane landfall in Sonora.
A major hurricane approaches Mexico
At 2 p.m. Mountain Standard Time on September 27, the U.S. National Hurricane Center placed Hurricane Polo about 445 kilometers west-southwest of Cabo San Lucas, with maximum sustained winds near 125 mph, or 205 km/h. That made Polo a Category 3 hurricane. The center forecast the storm to approach Baja California Sur on Monday, cross the peninsula Monday night and approach northwestern mainland Mexico early Tuesday. [1][2]
Hurricane warnings covered parts of the west and east coasts of Baja California Sur and a section of the Sonora coast. The advisory forecast 4 to 8 inches of rain, with isolated totals up to 12 inches, in parts of Baja California Sur; it forecast 4 to 6 inches, with isolated totals up to 8 inches, in parts of Sonora. The agency warned of life-threatening floods and mudslides, particularly on steep terrain, as well as destructive waves, rip currents and coastal flooding. [1][2]
Closures, ports and shelter capacity
The Baja California Sur government suspended classes statewide for Monday and Tuesday and said state, municipal and federal offices would also close on those days. Maritime activity was suspended. Airports were operating normally when the state notice was published, so travelers should check newer airport and airline notices rather than assume that status remains current. [3]
The state said its full Plan A and Plan B inventory comprised 169 shelter spaces with capacity for 33,192 people. La Jornada reported that the navy had deployed 2,923 personnel and described 111 shelters with capacity for 14,445 people. Those are not combined here: the 111 figure corresponds to the smaller initial shelter set, while the state total includes additional Plan B capacity. [3][4]
Why forecasts in early reports differ
Reuters reported earlier on September 27 that Polo was about 200 miles offshore and that landfall was expected Monday night. The later National Hurricane Center advisory refined the sequence to a Baja California Sur crossing Monday night and a separate approach to mainland Mexico early Tuesday. Forecast tracks and intensity can change; the latest official local warning should control emergency decisions. [5][1]
An earlier state notice discussed a possible Category 2 impact, while the later hurricane-center advisory forecast Polo at or near major-hurricane strength when it reached the peninsula. This is a change in forecast timing and intensity, not evidence that either source observed the storm at landfall. [3][1]
Who should keep checking alerts
Residents and visitors in Baja California Sur face the most immediate wind, flood and access risks. Coastal communities in Sonora and northern Sinaloa, fishers, port workers, school families and people traveling by road or air may also be affected. The reviewed material did not yet establish landfall damage, outages or the number of people using shelters. [1][3][4]
September 28 update: conditions expected to worsen Monday morning
In its 8 p.m. Mountain Standard Time advisory on September 27, issued at 0300 UTC September 28, the National Hurricane Center kept Polo at 125 mph, or 205 km/h, and located the center about 280 kilometers southwest of Cabo San Lazaro. The storm was moving north at 12 mph. The agency said conditions in Baja California Sur were expected to begin deteriorating Monday morning. [6]
The updated forecast kept Polo near major-hurricane strength as it reached Baja California Sur on Monday. It projected a crossing of the peninsula Monday night, followed by a mainland Mexico landfall early Tuesday as a hurricane. This update does not report observed landfall or damage; it records a newer forecast and should be superseded by later official warnings. [6][7]
September 28 morning update: 115 mph and a wider hurricane warning
At 2 a.m. Mountain Standard Time, or 0900 UTC, the National Hurricane Center lowered Polo's maximum sustained winds to 115 mph, or 185 km/h. The center was about 200 kilometers southwest of Cabo San Lazaro and moving north-northeast at 10 mph. A lower wind estimate than the previous advisory does not remove the emergency: the agency continued to warn of life-threatening winds and flash floods in Baja California Sur and Sonora. [8]
Mexico upgraded the hurricane watch on the east coast of Baja California Sur from north of Santa Rosalia to Bahia San Juan Bautista into a hurricane warning. The forecast continued to bring Polo's core across the peninsula late Monday afternoon or evening, briefly over the Gulf of California, and into mainland Mexico early Tuesday. These remain forecasts; the reviewed advisory did not yet report landfall or a verified damage total. [8][9]
September 28 midday update: core 140 kilometers offshore and rainfall forecast raised
At 8 a.m. Mountain Standard Time, or 1500 UTC, Polo remained a 115 mph Category 3 hurricane. Its center was about 140 kilometers west-southwest of Cabo San Lazaro and moving northeast at 10 mph. The National Hurricane Center expected the core to cross Baja California Sur during the evening, move briefly over the Gulf of California and reach southern Sonora Tuesday morning. [10][11]
The new advisory raised the broad Baja California Sur rainfall forecast to 6 to 12 inches. For Sonora, it forecast 4 to 6 inches with isolated totals up to 8 inches. The agency continued to warn of significant coastal flooding, destructive waves and life-threatening flash floods. Its forecast discussion also said moisture from Polo and post-tropical Odalys could contribute to heavy rain and flash flooding in the southwestern United States and southern High Plains later in the week. [10][12]
This is still a forecast update, not a landfall or damage report. At the advisory time, the reviewed official material did not establish verified damage, outages or shelter occupancy. [10]
September 28 afternoon update: dangerous conditions begin with the center 75 kilometers offshore
At 2 p.m. Mountain Standard Time, or 2100 UTC, the National Hurricane Center placed Polo about 75 kilometers west-northwest of Cabo San Lazaro. Maximum sustained winds remained 115 mph, or 185 km/h, and the Category 3 hurricane was moving northeast at 12 mph. The agency said life-threatening winds and flash flooding were beginning in Baja California Sur. [13]
The center was forecast to move inland along the peninsula's west coast later Monday evening, cross the Gulf of California and reach southern Sonora Tuesday morning. The National Hurricane Center expected Polo to be at or near major-hurricane strength at the Baja California Sur landfall and still a hurricane at mainland landfall. The 2100 UTC advisory had not yet reported an observed landfall or damage total. [13]
Sonora suspended afternoon classes in selected municipalities on September 28 and statewide classes on September 29 and 30, according to El Financiero's Spanish-language report. La Jornada reported closed beaches, suspended maritime activity and renewed calls for residents in Comondu, Loreto and Mulege to use shelters if needed. These local measures describe preparation, not proof of damage or shelter occupancy. [15][14]
The advisory also flagged the possibility of damaging winds in parts of southern New Mexico and far western Texas late Tuesday and Tuesday night. Residents should use the latest local warnings because the storm's track and intensity remain changeable after the reviewed advisory. [13]
September 29 early update: Polo about to make landfall at 115 mph
At 8 p.m. Mountain Standard Time on September 28, or 0300 UTC September 29, the National Hurricane Center located Polo about 125 kilometers north of Cabo San Lazaro and 155 kilometers south of Santa Rosalia. Maximum sustained winds remained 115 mph, or 185 km/h, and the Category 3 hurricane was moving northeast at 13 mph. The center said Polo was about to make landfall and expected the eye to cross the coast within the next couple of hours. [16][18]
Hurricane conditions were already occurring in Baja California Sur. The forecast took the center across the peninsula and Gulf of California overnight, with a second landfall in Sonora Tuesday morning while Polo was still a hurricane. The National Hurricane Center expected rapid weakening after the storm moved inland, but it maintained warnings for destructive winds, flash flooding and coastal hazards. [16][17]
Mexico's weather service forecast 150 to 250 millimeters of rain in parts of Sonora on Tuesday, 50 to 75 millimeters in parts of Baja California Sur and wind gusts of 150 to 170 km/h along the Sonora coast and south. These Spanish-language figures use a different national forecast product from the U.S. advisory and are reported separately rather than converted into a combined range. [19]
Reuters reported residents buying water, diapers and milk as beaches and maritime activity closed, and General Motors said it temporarily suspended work at a Coahuila plant because of disruption linked to Polo. The reviewed 0300 UTC advisory still did not report an observed landfall point, verified damage total, outage count or shelter occupancy. [20][16]
September 29 landfall update: likely Category 2 south of Las Barrancas
The National Hurricane Center said Polo made landfall around 0600 UTC September 29 on the west coast of Baja California Sur, just south of Las Barrancas. Its corrected forecast discussion said the exact intensity at landfall remained somewhat uncertain, but the available microwave and scatterometer data indicated Polo was likely a Category 2 hurricane with maximum winds in the 90-to-95-knot range, roughly 105 to 110 mph. [22][23]
At 0900 UTC, after the center had spent about three hours over land, Polo’s maximum sustained winds were estimated at 80 mph, or 130 km/h. The center was near 26.2 degrees north and 111.9 degrees west, moving northeast at 10 mph. Hurricane-force winds and life-threatening flash flooding were continuing in Baja California Sur. [21][22]
The 0900 UTC forecast called for Polo to cross the peninsula and make a second landfall in southern Sonora late Tuesday morning while still a hurricane, followed by rapid weakening inland. Forecast rainfall remained 6 to 12 inches in parts of Baja California Sur and 4 to 6 inches in southern and central Sonora, with isolated totals up to 8 inches. [21]
Early Spanish-language coverage by El País described the initial landfall as Category 3, reflecting the stronger estimate available around midnight. The National Hurricane Center’s later corrected discussion reassessed landfall as probably Category 2 after receiving additional observations. The later official estimate controls this update, while the uncertainty is retained. No reviewed source had yet established a verified damage, outage, casualty or shelter-occupancy total. [24][22]
