A strong anticyclone is pumping cold air to the south-west of the Mascarene islands. Notice the cold front is approaching our island. Those who love winter conditions (especially strong wind) will be happy. No significant precipitation is expected. Stay tuned for updates!

Strong wind, rough seas and a relative drop in temperature are expected over the Mascarene islands as from Friday 28 August due to a strong anticyclone coming from the south-west. The strong wind (fuchsia color) is particularly noticeable in the ECMWF animation. Refer to official forecasts from local authorities.

Historical cyclones: Hollanda (1994) remains one of the most unforgettable devastating tropical cyclone since the last 30 years. Notice that the most dangerous part of the cyclone (eastern quadrant) struck Mauritius, according to the cyclone track. The symbols (color and configuration) have been reworked and improved to comply with southern hemisphere convention.
Here are some facts:
Formation: Tropical depression formed Feb 6 south of the Chagos archipelago from an active monsoon trough; moved SW steered by a southern ridge
Intensification: Became Moderate Tropical Storm Hollanda (Feb 8); tropical cyclone with a small 20 km eye (Feb 9)
Peak/landfall: Peak winds 155 km/h (MFR) on Feb 10; struck Mauritius that day at peak intensity
Aftermath: Weakened while turning south; trough turned it east on Feb 13; became extratropical Feb 14
Mauritius impacts:
Wind gusts of 216 km/h in Port Louis
Rainfall up to 711 mm at Mare aux Vacoas
450 houses destroyed/severely damaged → 1,500+ homeless
~30% of trees downed; half the island lost power
Severe crop damage — nearly half the sugar crop destroyed, requiring government replanting assistance
2 deaths, $135 million in damage
Réunion impacts:
Highest rainfall from the storm: 741 mm at Grand Coude
Crop and power line damage

The animation shows the symbolic 1892 cyclone that devastated Mauritius in April. Notice how it accelerated once it struck the island (equatorward leg tracking west-southwest into the vertex, then accelerating south-east under mid-latitude westerlies after recurvature) and the symmetry of its track. Here are some facts:
· Date: struck Mauritius on 29 April 1892 , an intense cyclone directly struck the island of Mauritius.
· Intensity: winds reached 195 km/h (121 mph), with gusts to 216 km/h (134 mph), and pressure dropped to 947 mbar (27.96 inHg), breaking the 74-year-old record for the lowest recorded pressure on the island. The eye passage brought a lull of about 65 minutes.
· Death toll: consensus that over 1,200 killed, with the highest count at 1,262, and estimates of the wounded from 3,000 to 4,000 — by far the deadliest cyclone in recorded Mauritian history.
· Homelessness/destruction: left 50,000 people homeless and destroyed one-third of the capital, Port Louis.
· Port Louis damage: contemporary reports described half the town of Port Louis reduced to a heap of ruins, with severity so extreme that contemporaneous newspapers questioned whether the island would recover.
· District impact: Rose Hill was described as a field of devastation; Grand Port lost fifty people and Savanne twenty-five; eleven were crushed to death at Rivière du Rempart; few houses remained standing at Poudre d'Or, Grand Gaube, Cap Malheureux and Grand Bay.
· Economic cost: damage estimated at £2,000,000 (1892 GBP), roughly $9.75 million USD
· Warning failure: the observatory's last telegram underestimated the storm, saying winds would probably not exceed 90 km/h (56 mph) — the final warning before the telegraph lines snapped; officials then resorted to firing a cannon, followed by a gunshot, to alert residents.
· Vulnerability factor: most houses on the island were built of wood, with storm shutters as the main defense against high winds.
· Historical ranking: alongside the cyclones of 1868 and 1945, and later Carol in 1960, it's remembered as one of the island's most devastating storms— but 1892 remains the deadliest on record.

Hello everyone! The animation is a 3D picture of Port-Louis region and highlights its topography which is prone to flood during heavy rain episodes, particularly when moist-trade inflow of wind coming from the north-west direction. Obviously, the mountain ranges provide the uplift needed for cloud formation and can eventually lead to entrainment (regeneration of clouds due to orographic lifting). The following factors are relevant in this area during heavy rain:
1.Rapid runoff concentration
2.Funnel effect
3.Reduced infiltration in the urbanized zone (Rainfall runs off almost entirely over impervious surfaces (roads, roofs, pavement)
4.Short, steep river/ravine catchments
5.Low-lying outlet at the harbor
The animation is best viewed on large screen and the followers of this page will be able to appreciate high quality products in the future, especially during the upcoming summer season and El-Nino event.
Stay tuned for updates!

For info: A cluster of earthquakes occurred today, 15 August in Indonesia, one of which with magnitude 7.7 and triggering local tsunami warnings. The earthquakes occurred almost simultaneously as shown in the animation.
The second animation shows recent major earthquakes around the world.

The animations show latest satellite pictures for the Mascarene islands. Notice that cold air is remaining at higher latitudes.
The picture displays the expected temperature and wind speed for elevated regions in Mauritius and Rodrigues island. Wind speed is expected to pick up for both islands in the coming days.
Refer to official forecasts from local authorities.

The first picture is a recent basin-scale Tropical Cyclone Heat Potential (TCHP) for the Indian Ocean region. As the name suggests, it is the availability of heat in the ocean for potential cyclogenesis. Meaning of color variation:
Magenta: Low, Green/Yellow: High.
Notice that the green/yellow color is actually located in the northern hemisphere since we are right in the heart of austral winter in the southern hemisphere.
The second picture is a recent basin-scale sea surface temperature for the Indian Ocean region. Notice the temperature variation from lower to higher latitudes.
The animation shows the ocean current in the Indian Ocean.
