The Tanzanian government has announced its preparedness to address potential impacts of the El Niño phenomenon following a warning from the Tanzania Meteorological Authority (TMA). During a stakeholder meeting on disaster management held on June 24, 2026, Colonel Selestine Masalamado from the Prime Minister's Office stated that a National Emergency Plan draft has been prepared to enhance readiness and response measures.

Tanzanian Prime Minister Dr. Mwigulu Nchemba has urged citizens and leaders at all levels to take precautions and prepare early for potential effects of heavy rains linked to El Niño, including flooding. According to Michuzi Blog, he made the appeal on Sunday, September 6, 2026, while addressing residents of Ilongero Constituency in Singida District during a working tour. He also directed that a tender for constructing 11 kilometres of the Igauri–Ilongero road be announced within September.

Climate prediction scientists announced in June 2026 that a super El Niño had formed, expected to be one of the strongest on record. This phenomenon occurs when the Pacific Ocean's surface warms unusually, impacting global weather patterns and potentially leading to extreme events like droughts and floods. In southern Africa, previous cycles have resulted in severe hot and dry conditions, affecting millions and threatening marine life such as seals and sea lions.

The Tanzania Meteorological Agency (TMA) has received five vehicles valued at 300,000 US dollars from the United Nations Development Programme (UNDP) to enhance its weather monitoring and early warning services. This support aims to improve data collection from monitoring and observation stations throughout Tanzania, thereby strengthening the agency's capabilities in providing timely weather information.

The Nigerian Meteorological Agency (NiMet) has issued a flash-flood risk alert for the period from July 1 to 10, 2026, indicating that intensified rainfall is expected. The alert specifically mentions that Lagos, Sokoto, Imo, and 24 other states are at high risk of flooding during this time.

Umar Mohammed, the Director General of the Nigeria Hydrological Services Agency (NiHSA), stated that the recent severe floods in Lagos State and other areas were anticipated. He warned that more heavy rains and floodwaters are expected to continue for up to 12 weeks.
