Somalia Rainfall Forecast - Issued: 27 November 2020

The last few days saw increased rainfall amounts in parts of Somaliland and Puntland which were associated with the passage of Tropical Storm GATI. Some stations like Bossaso recorded 128 mm surpassing its annual average rainfall (50mm) in just a single day on 23 November 2020. Caalulla which had not received any rains in the year since March also saw significant rains of 76 mm on the same day. Other stations within the coastal areas of Bari, Sanaag, Woqooyi Galbeed and Adwal regions also recorded moderate to heavy rains. The storm which was characterized by strong winds and heavy rains led to loss of human lives, livestock death and destruction of properties. On the other hand, the unusual heavy rains in the area also led to immediate and short term recharge of subsurface water sources and pasture growth especially in Somaliland which has had a prolonged dry period since September 2020. However, these rains are not sufficient to cater the water deficit in the area. The three and seven days cumulated rainfall forecast (Map 1 &2) is pointing towards light rains in scattered areas in southern regions and moderate rains within in Lower Juba. Light rains are foreseen in the Ethiopian highlands during the forecast week. Hot and dry conditions will persist in Somaliland and Puntland with the rainy season coming to an end. River levels along the Juba and Shabelle basins remain within the normal ranges with no risk of flooding given the rainfall forecast. There remains a great concern in Somaliland and a few other places in the country due to insufficient rains during the Deyr season. With no more rains expected until the next rainy season in April 2021, the condition could deteriorate further towards a drought situation. This is confirmed further by the current climate models confirming a higher certainty of La Niña conditions persisting through March 2021. SWALIM and other technical partners are on the lookout of such developments.

Somalia Rainfall Forecast - Issued: 02 November 2020

There has been a significant decline of rainfall amounts across Somalia over the last week. In the north western regions of Awdal, Wooqoyi Galbeed and Toghdheer, a prolonged dry period has been observed since the last week of September 2020. Most stations in these regions recorded little or no rainfall during the month of October 2020. Similarly, parts of Puntland have not received any rains since the first week of October. There also remains a significant rainfall deficit in most parts of the southern regions and especially the Jubas and Lower Shabelle. The last week saw a reduction of river levels along the Shabelle River. Currently, levels are within normal in Belet Weyne and Bulo Burti districts while the mid and lower reaches are still at high levels. In Agfooye, the levels are at full capacity and most parts of the riverine areas remain inundated with massive displacement being reported in the area. River levels along the Juba increased sharply in the last one week reaching alarming levels in Bardheere. This was due to heavy rains in the upper reaches of the Ethiopian side which also led to river flooding in Dollow. The last three days have however seen a reduction of the levels along the channel. The cumulative rainfall forecast for this week suggests a significant reduction of rainfall amounts across the country with light rains along the southern coastal areas. Little or no rainfall is foreseen in the Ethiopian highlands. This will subsequently lead to a decrease in river levels especially along the Shabelle river. Given the rainfall forecast and current situation along the two rivers, flooding is likely to persist in Lower Shabelle riverine areas. There is no risk of flooding foreseen along the Juba River. There is however a great concern of moisture deficits across the country especially in the rain fed agricultural areas of the southern regions. Drought conditions are foreseen if the trend continues.

Tropical Storm Update - Issued: 24 November 2020

Tropical Storm GATI weakened leaving a trail of destruction in parts of Bari and Sanaag regions The tropical storm GATI has weakened further and is moving westwards with a speed of 7KPH. It is expected to dissipate in the next 12 hours. The storm left behind a significant physical and economic damage especially in Bari region. More than 700 houses were destroyed, several boats and fishing gears damaged and loss of a large number of livestock. This has led to loss of livelihood for most families and may take time and huge financial input to replace the loss. There was a reduction of rainfall amounts and wind speeds in the last 24 hours in many areas along the storm path. This trend is expected to continue as the storm gets weaker and the situation will stabilize thereafter. The sea conditions are still rough over the coastal areas of Puntland and Somaliland and fishermen are advised not to venture into fishing operations for today. The storm impacts will continue to be experienced today in Sanaag and Woqooyi Galbeed coastal areas but with lesser magnitude compared to what was experienced Bari in the last two days. The rainfall forecast for Somaliland and Puntland is calling for moderate rains in the next couple of days and a reduction towards the end of the week. The Ethiopian highland and southern parts of the country are also expected to experience moderate to heavy rains in the course of the week. Given the three days rainfall forecast, flash floods may occur in Toghdheer, Sool, Galgaduud and Mudug regions within the areas neighboring Ethiopia.

Some villages continue to be under water since August 2020. River levels along the Juba increased slightly during the last few days due to moderate rains in the Ethiopian highlands. The cumulative rainfall forecast for this week indicates moderate to heavy rains in many areas across the country. In the western parts of Somaliland and south of Bari region in Puntland the rains will be less. The Ethiopian highlands whose soil moisture is already saturated due to heavy rains since July 2020 will see an increase of rainfall amounts this week. This will subsequently lead to a further increase in river levels especially along the Shabelle river. Given the rainfall forecast and current situation along the two rivers, High Risk of flooding remains along the lower reaches of Shabelle while along the Juba River there is Moderate Risk of flooding foreseen . There is a also a High Risk of flash floods in the built up low lying areas especially in Galgaduud, Mudug, Bay and Bakool regions
