Deep Depression ARB 02 was a weak yet costly tropical cyclone which caused extensive damage and loss of life in Yemen.

Poor drainage practices and an invasive species of weed contributed to the floods, which damaged or destroyed 6,505 houses, leaving about 25,000 people homeless.

The floods killed 180 people and severely disrupted the livelihoods of about 700,000 residents of Hadhramaut and Al Mahrah governorates, mostly farmers whose fields were washed away.

Nations in the region, including Saudi Arabia and the United Arab Emirates, sent money and supplies to help rebuild the damaged infrastructure and houses.

On October 11, an active phase of the Madden–Julian oscillation, in conjunction with an equatorial wind burst, produced twin areas of convection in the central Indian Ocean on both sides of the equator.

[1] The northern hemisphere system originated in the Bay of Bengal, and moved westward for much of its duration,[2] steered by a ridge to the north along 15º N. On October 16, a low-pressure area developed over southern India near Kanyakumari.

On October 19, the India Meteorological Department (IMD) classified the low as a depression about 725 km (450 mi) southeast of the Yemeni island of Socotra.

[3] On the next day, the JTWC discontinued advisories,[2] and the IMD downgraded the system further to a remnant low to the northeast of Cape Guardafui, Somalia.

[3] The JTWC continued tracking the system as it moved northwestward, and the circulation made landfall near Ash Shihr in southeastern Yemen late on October 23, losing its identity shortly thereafter.

[21] The government sent search and rescue teams into the flooded areas to help stranded residents, although strong winds in the region disrupted these efforts in the immediate aftermath.

On October 27, the Yemen government requested assistance from the international community, unable to provide disaster assessments or cope with the rebuilding.

The storm affected areas of Yemen that already had poor infrastructure and lack of food, and were generally under a state of political unrest, which made recovery difficult.

[22] Yemen's Deputy Prime Minister for Internal Affairs coordinated the relief efforts, in conjunction with the governors of the most affected areas.

The Ministry of Public Works helped reopen roads, which allowed for the transport of relief goods, and the damaged Sayun Airport was repaired to withstand future floods.

The president also utilized the nation's military to assist storm victims,[18] and sent aircraft with tents, food, and medicine to the worst hit areas.

[21] Ultimately, the Red Cross assisted over 70,000 storm victims through health programs,[24] and also helped residents cope with stress, hygiene promotion, and other ongoing vulnerabilities to their livelihoods.

[23] Various agencies under the United Nations assisted in the recovery;[14] the World Health Organization provided medical kits to the worst hit areas, capable of helping 10,000 residents each for three months.

The World Bank led the assessment efforts, estimating the cost of recovery at $1.046 billion, mostly toward rebuilding houses, regrowing crops, and restoring social services.

The World Bank also provided $41 million toward the Yemen Flood Protection and Emergency Reconstruction, which rebuilt vital infrastructure and ensured they were flood-proof.

[26] The Organisation of the Islamic Conference declared the situation a "national catastrophe" and started a drive to collect funds for the relief of flood victims.

[27] The United Arab Emirates Red Crescent assisted in the reconstruction work, sending $27.3 million to rebuild 1,000 houses;[14] 750 of these were completed by December 2009.
