Thunderbolts Without Rains

But Late Impacts

Mauritius, specially the region of Port Louis, was struck by Thunderbolts during 9.00 to 9.30 pm on Wednesday 26 April 2017. The Cumulonimbus Clouds were visible during the flashes of Lightning and Thunder, but not a drop of Rain fell.

The Mauritius Meteorological Services (MMS) had mentioned, yesterday, about a ‘line of instability’ in its routine bulletin. In fact, there was a Cold Front which was moving from West to East, preceding an Anti-Cyclone with 1020 hectopascals, as explained in article ‘Winter Season 2017’. It is presumed that this system interfered with the South-East Trade Wind (SETW) which was propelling DRY AIR towards the Mascarene Islands.

Whole day of Wednesday 26 April was showing Fair Weather with some scattered whitish CUMULUS Clouds. So, RAINS could not be triggered, except a maximum of 7 mm in the South. Temperature was 330C and Humidity varied between 68-88%, as recorded by the MMS.

The MMS issued on:

<< Wed, Apr 26, 2017

SPECIAL WEATHER COMMUNIQUE FOR MAURITIUS ISSUED AT 21H00 THIS WEDNESDAY 26 APRIL 2017 VALID FOR TONIGHT.

GENERAL SITUATION :

Active clouds associated with the instability line coming from the North are actually influencing the weather over the island.

These clouds are causing an electric storm with localised showers mainly to the North, the East and over the Central Plateau of the island.

The showers will be moderate at times with thunderstorms and gusts

Temporary water accumulations are expected in certain places and the visibility may become poor in showers.

PRECAUTIONS :

1. In case of thunderstorms, the public is advised to remain in safe places, avoid sea ventures and sheltering under trees.

2. Road users are advised to be very cautious.>>

 

The Mauritius Meteorological Services issued a second Weather Bulletin after half an hour:

<< WEATHER NEWS FOR MAURITIUS ISSUED AT 21H30 THIS WEDNESDAY 26 APRIL 2017.

  

GENERAL SITUATION:

Clouds associated with an instability line are influencing weather over our region. 

FORECAST FOR THE NEXT 24 HOURS:

Cloudy over the whole island with thundery showers mainly over the Central Plateau, the East and the North.

The minimum temperature will be between 18 and 21 degrees Celsius over the Central Plateau and between 23 and 25 degrees Celsius along the coasts.

The weather will remain cloudy in the morning with showers and isolated thunder, becoming less frequent in the afternoon.

The maximum temperature will be between 25 and 27 degrees Celsius over the high grounds and between 29 and 31 degrees Celsius along the coastal regions.

Wind from the Eastern sector at 15 to 20 km/h. 

Sea rough beyond the reefs with South-Westerly swells.  Ventures in the open sea are not advised.>>

However, on Thursday morning 27 April 2017, the whole sky was covered with a blanket of NIMBOSTRATUS Cloud.  

Thunderbolts Started striking again as from 2.20 pm until 4.00 pm, triggering Precipitations. Everywhere it was wet.   

   

Watch VIDEO below.

 

The MMS released another Special Communique at 2.30 pm on Thursday 27 April 2017:

<< SPECIAL COMMUNIQUE FOR MAURITIUS ISSUED AT 14H30 THIS THURSDAY 27 APRIL 2017 VALID FROM 10H00 FRIDAY 28 APRIL UP TO 16H00 SUNDAY 30 APRIL 2017.

GENERAL SITUATION :

A strong anticyclone to the South of the Mascarenes will influence the weather as from Friday evening. It will cause a windy and relatively cold weather. 

OUTLOOK FOR THE WEATHER OVER THE WEEK-END :

Weather will be cloudy with intermittent rain mainly in the East, the South and the Central Plateau. The rain will be moderate at times with isolated thunderstorms particularly from Saturday to Sunday morning. 

Temperature will be 1 to 2 degrees Celsius below the seasonal mean with a maximum of 24 degrees Celsius on the Central and a minimum of 20 degrees Celsius.

The maximum on the coastal areas will be 27 to 29 degrees Celsius and the minimum between 23 and 25 degrees Celsius. 

Wind will blow from the East-south-east 20 to 30 km/h in the mean with gusts which may reach 70 km/h in exposed areas. 

Sea will be very rough with 4 to 5 metres South-westerly swells in the open seas.

The public is strongly advised not to venture at sea as well as in the lagoons.>>

Verify with the MMS here.

NB: A maximum of 33.2 mm of Rain showered Mauritius on 27 April 2017.

Refer to the picture of JTWC. Seas Swells are mentioned to reach 12 ft  (4 mts) near the Mascarene Islands and to 18 ft (6 mts) beyond, higher than mentioned by the MMS.

COMMENTS

ü  1) Very Intense Tropical Cyclone FANTALA, the Record-Breaker phased out out on 25 April 2016 after its formation on 12 April. It is worthwhile to reiterate that Tremendrous Thunderbolts which occurred (last year) during whole night of Thursday 28 April 2016 in Mauritius, caused disastrous impacts. Rainfalls of 91.2 to 125.2 mm caused localized Flash Floods and Black out affected ectricity Supply in 10,000 households. The following day all scholls were kept closed. Futhermore, Rodrigues lived the same experience on 30 April, two days later when the Weather System moved towards the East. See picture.

      

2) Finally, the Mauritius Meteorological Services (MMS) announced about the arrival of Wintery Conditions with a:  

  1. Strong Anti-cyclone’;
  2.  relatively cold weather’ withdecrease of 1-2 degrees in Temperature;
  3. 20 to 30 km/h in the mean with gusts which may reach 70 km/h’ and
  4. ‘Sea will be very rough with 4 to 5 metres South-westerly swells in the open seas’.

All these give sufficient support to the PREDICTION of an Early Winter as mentioned in previous article: Winter Approaching Earlier With Rains and Summer 2016-2017 Departing with Late Showers’. This PREDICTION was made on Sunday 16 April 2017, that is, 10 days earlier than the MMS.

In other words, Climate and Weather Forecasts cannot be done by relying only on Scientific Data and Information. Application of Traditional, Indigenous and Local Knowledge/Practices (TILK/P) and Observations of Clouds and of the Atmosphere from the Ground are complementary components. These have been duly and rightly promoted by the World Meteorological Organization (WMO) on 23rd March ‘World Meteorological Day’ whose theme was UNDERSTANDING CLOUDS’. Refer to article published earlier.

On one side, all the National Hydrological and Meteorological Services (NHMS) of the whole world are requested to stop being amateurs.  Professionalism, Innovation and Dynamism are required for proper implementing the Early Warning Systems, thereby providing better Protection and Safety for their respective population.

On the other side, the WMO is requested to see to it that all these together with the different themes of the WM Day be implemented and activated. The main reason behind all these is that there are many meteorological services which do not provide adequate data and information. As a result, lots of lives are being lost during calamites in many quarters. Such loopholes have been reported to the WMO President Mr David Grimes since 2013.

It is time to Watch VIDEO now. CLICK PHOTO below. 

Keep watch.
