Hikers in Hawaii were warned about encountering sudden freezing rain as a severe winter storm brought cold temperatures to Haleakalā overnight on Thursday.
The National Weather Service (NWS) office in Honolulu issued a winter weather warning for the summit and the upper slopes of the Haleakalā volcano in Maui on Thursday. The severe weather will continue until 8 a.m. Friday morning local time.
Winter weather at Haleakalā was so severe that the Summit District of Haleakalā National Park closed on Friday, citing hazardous conditions. The park also canceled all of its sunrise reservations for the day, according to a report by National Parks Traveler. Meanwhile, reservations for the Hosmer Grove Campground were canceled for Thursday. Reservations, however, remained opened for Haleakalā crater, but the summit district warned backpackers to prepare for severe winter weather conditions and freezing rain.
NWS meteorologist Joseph Clark told Newsweek on Friday that typically, Haleakalā’s summit maintains temperatures above freezing, even in the winter months. However, freezing weather reached the volcano’s summit at 10,000 feet, and up to three tenths of an inch of ice was predicted to form as rain fell on the volcano’s upper slopes. Winds gusting as high as 60 miles per hour also were expected.
“A fast-moving cold front will bring freezing rain to the Summit and upper slopes of Haleakala tonight and early Friday morning,” the NWS’s Thursday warning said, adding that “significant icing was expected.”
The NWS said that “the front will move quickly east of Maui by Friday afternoon, and the chance for rainfall will diminish as temperatures gradually warm.”
The agency also urged people to postpone any travel plans to the Haleakalā summit given the severe, freezing conditions.
“A Winter Storm Warning means significant amounts of snow, sleet, and ice are expected or occurring. Strong winds are also possible,” the warning said. “This will make travel very hazardous or impossible.”
Snow and winter weather conditions are not uncommon at Hawaii’s high-altitude volcanos, which can reach 14,000 feet high. Earlier this season, 6 inches of snow fell at the peak of Mauna Kea, a volcano on the Big Island. However, the conditions are less common at Haleakalā, which is shorter than Mauna Kea.
“[Winter weather] is not as common as it is on the higher slopes of the Big Island,” Clark told Newsweek. “It’s less common to get winter weather [at Haleakalā], but it does happen.”
The severe weather comes as similar winter weather alerts were issued for every single U.S. state on Friday morning. A deadly winter storm gripped the nation on Friday and will be followed by frigid temperatures, with wind chill as cold as 70 degrees below zero in some northern states as an arctic blast follows the storm.

OLOWALU (HawaiiNewsNow) – A team of shark researchers from the University of Hawaii at Manoa have solved a longstanding mystery.
Biologists from the the Hawaii Institute of Marine Biology Shark Lab have identified the first-ever documented tiger shark mating hub.
Six years of acoustic tracking data led the team to pinpoint the area at Olowalu, Maui, leading them to new discoveries about the nature and timing of tiger shark mating and its correlation to Maui’s whale calving season.
This new finding challenges the understanding of tiger sharks as purely solitary animals.
“To our knowledge, no group mating site for tiger sharks has ever been identified. This paper adds an important piece to the puzzle of tiger shark reproduction,” said Carl Meyer, co-author of the study and principal investigator of the HIMB Shark Lab.
Researchers were able to show evidence that tiger sharks have a predictable seasonal gathering of mature males and females that coincides with humpback whale calving season in Hawaii.
Until this discovery, it was unclear how or if tiger sharks came together to reproduce or if mating was just a result of random encounters.
“Tiger sharks typically roam widely in what can seem like random patterns, so finding such a strong and consistent seasonal trend in their movements around Maui was unexpected,” said Paige Wernli, lead author of the study and a graduate student in the HIMB Shark Lab.
The years-long tracking data showed a predictable seasonal presence of both mature male and female tiger sharks at Olowalu, as well as physical evidence of mating activity.
The apparent mating hub happens during the time of year when humpback whale mothers and newborn calves arrive in the area.
The Shark Lab team says the correlation could mean that the sharks are positioning themselves near foraging opportunities, like vulnerable calves or placental falls.
“Mating and foraging on humpback whales may not be mutually exclusive,” Wernli said. “And both could influence tiger shark movement patterns in Hawaii.”
The tiger shark gatherings they observed were not dense but rather diffuse, spanning several kilometers over multiple months.
“This study expands our knowledge of tiger shark mating and challenges our conventional understanding of the term ‘gathering,’” said Meyer. “Together, the results suggest that both reproduction and food availability play key roles in shaping tiger shark movements in Hawaii.”
During the six-year study, the team was able to safely catch and implant transmitters in large sharks, then keep a vast network of underwater listening stations across the main Hawaiian Islands.
In the future, the Shark Lab team plans to use tags with cameras and other data collecting capabilities to document both their mating behaviors and shark-whale interactions.
This work was funded by the Hawaii Department of Land and Natural Resources and the Pacific Islands Ocean Observing System.
