The head of the government in eastern Libya, which lacks international recognition, asserted that the number of fatalities has surpassed 2,000, with a significant number of individuals reported as missing.
According to Jalel Harchaoui, an expert on Libya, he informed the BBC that the number of casualties might potentially escalate to a magnitude of "several thousand" individuals.
Authorities in the eastern region implemented a curfew, concurrently issuing directives for the closure of educational institutions and commercial establishments.
The cities of Benghazi, Sousse, Derna, and Al-Marj in the eastern region saw significant impacts.
In addition to the escalating number of fatalities, the Libyan Red Cross has reported the destruction of a minimum of 150 residential properties.
According to the news agency Reuters, the leader of the Red Crescent humanitarian network reported that a minimum of 150 fatalities had happened specifically in the city of Derna.
According to reports, two dams in Derna, a locality inhabited by an estimated population of 100,000 individuals, have purportedly experienced a collapse, resulting in the inundation of a significant portion of the region and the unfortunate loss of life for certain residents.
As a result, the authorities officially designated the port as a "disaster city".
According to Eastern Prime Minister Osama Hamad, during an interview with a Libyan news channel, a significant number of individuals are unaccounted for, estimated to be in the thousands, while the number of casualties has surpassed 2,000. He also stated that entire neighborhoods in Derna have been obliterated, resulting in the disappearance of their inhabitants, who were reportedly washed away by water.
On Sunday, Storm Daniel reached the coast, leading authorities to proclaim a state of extraordinary emergency.
During the current rescue operations, a total of seven members of the Libyan army have been reported as missing.
The source of the numbers provided by Mr. Hamad was not disclosed.
In addition to the eastern regions, the city of Misrata in the western part of the country also experienced the impact of the floods.
Online, there have been circulating movies of the storm that have not been verified for accuracy. Among these videos is a clip depicting a man being swept away by torrents of floodwater. Additional video footage depicts individuals who are confined to the rooftops of their vehicles.
In addition to educational institutions and commercial establishments, the storm prompted the closure of four significant oil ports.
The Benghazi-based administration has been engaged in addressing issues in the eastern region of the country, but the opposition government, which is internationally recognized and located in the capital city of Tripoli, has also been actively involved.
The Prime Minister, Abdulhamid Dbeiba, announced on Sunday that he has instructed all governmental entities to promptly address the consequences of the damage and floods. Additionally, the United Nations in Libya expressed its close monitoring of the storm and its commitment to delivering urgent relief aid to assist in the response endeavors at both local and national scales.
Since the demise of the longstanding leader Muammar Gaddafi in 2011, Libya has experienced a division into two competing governments, a situation that has persisted since 2014.
Following the occurrence of Storm Daniel, both governments have officially announced a period of three days designated for mourning.
Last week, Greece, Turkey, and Bulgaria were impacted by a severe event resulting in the loss of over a dozen lives.
On Monday, Egypt was preparing for the arrival of Storm Daniel. In the evening, the country's meteorological organization reported an increase in rainclouds over the northwestern shore.
Climate scientists have issued a cautionary statement regarding the correlation between global warming and increased water evaporation throughout the summer season, thus resulting in heightened storm intensity.
