Experimental Climate Monitoring and Prediction for Maldives – December 2018

HIGHLIGHTS

Monitored: During December, northern islands received rainfall slightly above than is normal for the season; and central and southern islands received below than normal. The Northern Islands have been having a rainfall deficit in the last year compared to normal rainfall, that increased up to 450 mm during December.  The Central Islands have an excess of 100 mm of rainfall during last year compared to the average while the Southern Islands are having an excess of 350 mm. The sea surface temperature around Maldives is normal.  
Predictions: IMD GFS model predicts up to 40 mm of rainfall in the central islands; up to 10 mm in southern islands on January 16th. On the 17th up to 70 mm of rainfall is expected in central islands and up to 40 mm in northern islands. On the 18th, up to 130 mm of is expected in the central and southern islands. 

In December, the northern and southern islands received up to 180 mm of total rainfall

Record rainfall in Maldives capital

Original Article - Link

Floodwaters caused damages in 117 homes and 20 people were evacuated. 

More than 100 homes needed assistance and two families were evacuated Wednesday as a torrential downpour flooded the streets of the capital.
The 223.5 millimetres of rain from 8am to 8pm was a record for the capital island, according to the Maldives Meteorological Services.
The previous record was 200 millimetres on December 11, 1998. The national record was 228.4 millimetres on the southernmost island of Gan on November 24, 2015.
The record rainfall in Malé caused flooding as many roads were inundated with up to two feet of water.
Soldiers and police officers were deployed to set up sandbags and operate pump stations. Volunteers from the local Red Crescent as well as scouts and girl guides joined the relief efforts along with staff from the city council and other offices.
Floodwaters caused damages in 117 homes and the National Disaster Management Centre helped relocate 20 people from two residences. Food and accommodation were arranged for the 11 adults and nine children at the Beehive Hotel.

Experimental Climate Monitoring and Prediction for Maldives – November 2018

HIGHLIGHTS

Monitored: During November, most parts of the country received rainfall below than is normal for the season by up to 120 mm. The Northern Islands have been having a rainfall deficit in the last year compared to normal rainfall, that increased up to 300 mm during November.  The Central Islands have an excess of 250 mm of rainfall during last year compared to the average while the Southern Islands are having an excess of 400 mm. The sea surface temperature around Maldives is above  0.5 ⁰C normal. 
Predictions: IMD GFS model predicts up to 40 mm of rainfall in the southern islands; up to 10 mm in northern and central islands on December 3rd and 4th. On the 5th and 6th up to 40 mm of rainfall is expected in southern islands and up to 10 mm in northern islands. Long Range Weather prediction simulations anticipate total rainfall up to 100 mm for central islands during December 1st-6th. 

In November, the southern islands received up to 450 mm of total rainfall.

Experimental Climate Monitoring and Prediction for Maldives – October 2018

HIGHLIGHTS

Monitored: During October, central parts of the country received rainfall above than is normal for the season by more than 240 mm; and most parts of southern islands and northern islands by up to 120 mm. The Northern Islands have been having a rainfall deficit in the last year compared to normal rainfall.  Also, the Central Islands have a slight excess of rainfall compared to the average while the Southern Islands are having a good year. The sea surface temperature around Maldives is above 1 ⁰C normal. This is extremely warm. 
Predictions: IMD GFS model predicts up to 40 mm of rainfall in the southern islands; up to 20 mm in central islands; and up to 10 mm in northern islands on November 11th, 12th and 13th. On the 14th, up to 20 mm of rainfall is expected in central islands and up to 10 mm in northern and southern islands. Long Range Weather prediction simulations anticipate total rainfall up to 75 mm for central islands during November 9th -14th. 

Central islands received rainfall above than is normal for the season by more than 240 mm.

Experimental Climate Monitoring and Prediction for Maldives – September 2018

HIGHLIGHTS

Extremely High Rainfall is forecasts for the North and Central Islands for the 1-6th October.
Monitored: 
During September, Southern Islands received rainfall above than is normal for the season by more than 240 mm; and Northern and Central islands received below normal rainfall. The cumulative rainfall for the last 365 days shows a 500 mm deficit for the Northern islands; 50 mm deficit for the Central islands; and an excess of 400 mm for the Southern Islands when compared to the past average.   The sea surface temperature around southern Maldives is below  0.5 ⁰C normal.

Predictions: IMD GFS model predicts up to 70 mm of rainfall in northern islands; and up to 10 mm in central and southern islands during October 3rd - 6th. On the 7th, up to 70 mm rainfall is expected in the northern islands; up to 40 mm in the central islands; and up to 10 mm in the southern islands. Long Range Weather prediction simulations anticipate total rainfall up to 300 mm for the northern and central during October 1st -6th. 

Southern islands received rainfall above than is normal for the season by more than 240 mm.

Experimental Climate Monitoring and Prediction for Maldives – August 2018

HIGHLIGHTS

Monitored: During August, Central and Southern Islands received rainfall below than is normal for the season by up to 120 mm; and northern islands by up to 90 mm. The Northern Islands have been having a rainfall deficit in the last year compared to normal rainfall.  Also, the Central Islands have a slight lack of rainfall compared to the average while the Southern Islands are having a good year. The sea surface temperature around Maldives is above 0.5 ⁰C normal.

Predictions: IMD GFS model predicts 10 mm of rainfall in the entire country on September 3rd and 4th. On the 5th and 6th, up to 10 mm rainfall is expected in the northern and central islands. On the 7th up to 10 mm rainfall is expected in the northern islands. Up to 20 mm of rainfall is expected in the northern islands; and up to 10 mm in the central and southern islands on the 8th. Long Range Weather prediction simulations anticipate total rainfall up to 25 mm for the entire country during September 1st -6th. 

Central and Southern islands received rainfall below than is normal for the season by up to 120 mm

Experimental Climate Monitoring and Prediction for Maldives – July 2018

HIGHLIGHTS

Monitored: During July, Southern, some Central and Northern Islands received an excess of rainfall than is normal for the season by up to 90 mm. However, the Northern Islands which had been having a rainfall deficit in the last year is not fully recovered from the below normal rainfall.  The Central Islands have a slight excess of rainfall compared to the average while the Southern Islands are having a good year. The sea surface temperature around Maldives is near normal.

Predictions: IMD GFS model predicts up to 10 mm of rainfall is expected in the entire country on August 7th and 8th. On the 9th, up to 10 mm rainfall is expected in the northern islands. Up to 20 mm of rainfall is expected in the northern islands; and up to 10 mm in the southern islands on the 10th. Long Range Weather prediction models simulations anticipate total rainfall up to 25 mm for the entire country during August 5th -10th. 

Central islands received up to 450 mm of total rainfall in July.
