The highest 24-hour rainfall of India was reported on September 13, 1974 (98.55/cm) at Cherrapunji (Sohra), a hill station located in the NE India. 

• Colaba observatory in Mumbai recorded 58 cm rainfall on July 5, 1974. 

• Chennai (SE peninsula) received rainfall of 45 cm on November 25, 1976 as its highest ever recorded rainfall on a single day. 

• Thiruvanathapuram (southwest peninsula) recorded 40 cm rainfall on October 18, 1964, as its all time record in 140 years. 

• Mahabaleshwar (northwest peninsula) reported 44 cm during 1961-1980 as its record highest for all the months. 

• Mount Abu (northwest India) reported 56 cm rainfall on September 19, 1973.

• Motihari (northeast India) recorded 46 cm rainfall as its highest in 93 years. 

• Dehra Dun (north India) recorded 49 cm rainfall on July 25, 1966 as the highest rainfall for 100 years. 

• The annual mean rainfall of Phalodi, (northwest India) is about 26 cm, but on July 12, 1964, it reported 23 cm rainfall in just 24 hours. 

It is observed that out of 165 stations, 128 (77.6 %) reported their EPRE during the bi-decadal period 1961-1980. Further, 85 stations have recorded the rainfall = 20 cm/day. 4.1.2. Period : 1981-2000 

High rainfall instances reported at some stations during 1981-2000 are shown in Tables 2. Bold digits indicate the rainfall = 40 cm/day. Some notable instances are described below. • Cherrapunji recorded 156 cm rainfall on June 16, 1995 crossing its previous all time highest of 98.55 cm reported on September 13, 1974 (Table 1). It had also set a record for the northern hemisphere overtaking the earlier record held by Paishih (Taiwan) of 125 cm reported on September 10-11, 1963 (Randall et al., 2007). However, this Cherrapunji record was exceeded after ten years, as Isla Mujere (Mexico) got 163 cm rainfall on October 21-22, 2005 (http://wmo.asu.edu/). Still, it remains as a record for the Indian sub-continent.

• Bhira, a station on the windward side of the western ghats (northwest peninsula) got 71 cm rainfall on July 24, 1989 as its all time highest during the period data availability from 1932. The rainfall was associated with the passage of a depression moving towards northwest India. 

• Beed in Marathwada, subdivision, reported its all time highest rainfall (32 cm) on July 24, 1989 under the influence of the same depression mentioned above.

• Santacruz (Mumbai) received 40 cm rainfall on June 10, 1991 exceeding its previous highest rainfall of 38 cm reported on July 5, 1974. 

• Jodhpur (NW India) recorded 29 cm rainfall on August 5, 1996. It is noteworthy that its annual mean rainfall is about 36 cm. • Rainfall of 49 cm on July 7, 1991 at Silchar (NE region) has crossed its previous all time highest (29 cm) recorded in 1893. • Koida (SE peninsula) recorded 67 cm rainfall on June 17, 1996. 

4.1.3. Period: 2001 – 2009 

EPRE for this period from 2001 to July 2009 are depicted in Table 3. A few typical cases are highlighted below. • Amini Divi recorded 117 cm rainfall on May 6, 2004 and created a record for the north Indian ocean. It was associated with a passage of a tropical cyclone. It is worthwhile to mention that this station recorded 184 cm rainfall during just three days viz. May 5-7, 2004 ! • Mumbai (Santacruz) experienced exceptionally heavy rainfall of 94 cm on July 27, 2005 (Table 3). Some other nearby stations also reported very high rainfall (e.g. Vihar lake : 105 cm) and the city was hit miserably due to unprecedented deluge. It was mainly due to the cloud burst and intense thunderstorm activity embedded in the monsoon circulation (Vaidya and Kulkarni, 2007). The peculiarity of this event was that the activity was highly localized to the northern part of the city as Colaba, just 25 km south of Santacruz reported only 7 cm rainfall on the same day. • Ratnagiri, a coastal station about 230 km south of Mumbai recorded 64 cm rainfall on May 31, 2006 surpassing its previous all time highest (31 cm) recorded on June 30, 1953. • Mahabaleshwar reported its all time highest 46 cm on 3 August 2004. However, it was also exceeded on 11 August 2008 with 49 cm rainfall. 

• Veraval (Saurashtra and Kutch) reported 50 cm rainfall on 16 July 2009 surpassing its highest (36 cm) recorded in the previous decade i.e. on July 26, 1996 (Table 2).

4.2. Rainfall events exceeding 50 cm/day 

Sixty nine stations which reported the rainfall = 50 cm/day have been identified over the region for the period: 1875- 1990 (Dhar and Nandargi, 1998). Out of them, 45 cases have occurred up to 1960 (86 years) and 24 during 1961-90 (30 years). Afterwards, following stations (as per the data of the study) have joined this elite ‘R50’ club. 

Amini Divi, Koida, Malda, Kaleswaram, Motihari, Songadh, Ratnagiri, Poladpur (west coast), Vihar lake, Santacruz (and the stations around Mumbai which recorded very heavy rainfall on July 27, 2005), Veraval and Mangrol (Saurashtra and Kutch) recorded on 16 July 2009. 

4.3. Surpassing of all India records 

Mawsynram, a station (northeast India) recorded 98.96 cm rainfall on July 10, 1952. It was the record as the highest 24-hour rainfall over the India (Thapaliyal and Kulshrestha, 1992). During last 15 years, three stations viz. Cherrapunji, Amini Divi and Vihar lake have crossed this record. It is further noticed that five of the top seven rain events have occurred after 1970 (Table 4), indicating the rise in the intensity of EPRE in the recent times. 4.4. High rainfall spells on different time scales 

The cases of extreme rain events for 24 hours are described above. There are some instances of very high rainfall reported from 1995 on different time scales. They are described below. 4.4.1. Short duration record rainfall 

On June 16, 1995, Cherrapunji recorded 42 cm rainfall in just one hour exceeding the world record of 30.5 cm held earlier jointly by Holt, MO and Kilauea sugar plantation (Randall et al, 2007). During June 15-16, 1995, same station reported 249 cm rainfall (Pai and Guhathakurta, 2007), crossing 48-hour world record of 247 cm of Aurere, La Reunion, occurred during January 8-10, 1958 (http://wmo.asu.edu/). 4.4.2. Record rainfall over desert area Extreme northwest region of India is a part of the Thar desert. It received record rainfall of 55 cm during August 16-25, 2006 i.e. just in 10 days (Jayanthi et al, 2006). More than 100 persons lost their lives, many animals died and lot of destruction was reported to the agriculture sector due to the floods. 

4.4.3. Un-seasonal heavy rainfall instances 

Chennai reported 21 cm rainfall during the last week of February 2000. Getting more than 20 cm rainfall in the last week of February is an event of the century for the city (Asokan and Nair, 2000). However, it was a blessing to the city dwellers as these un-seasonal rains relieved them from acute scarcity of the water caused by deficient rainfall during the NE monsoon season. 

6 

4.4.4. Excess rainfall on the seasonal and annual scale over a semi-arid location 

Pune city situated on the leeward side of the western ghats, falls under the semi-arid or the rain-shadow zone with the mean annual rainfall about 72 cm as against about 250 cm on the windward side. During 2004-2007, it recorded more than 80 cm rainfall consecutively in four summer monsoons. It was significantly high as compared to the seasonal normal- 55 cm. In 2005 and 2006, the city reported 116 cm (134 cm) and 110 cm (127 cm) rainfall in the summer monsoon (calendar year) respectively crossing its earlier annual record 124 cm which was established in 1892. 

4.4.5. Rainiest station in the world 

Annual mean rainfall of Mawsynram is 1151 cm considering the data of past 66 years i.e. for the period : 1940-2005 (Pai and Guhathakurta, 2007). It is more than other two most rainy stations in the world viz. Waialeale, Hawaii, USA (1144 cm) and Cherrapunji (1115 cm).

First Ever Tornado to be Briefly seen over Chennai ...

Chennai: Robert Gagarin (58) of Uthandi  is not a habitual star-gazer. He just happened to be on the rooftop of his house in time to catch a glimpse of a tornado  in the distance.

The day was Thursday last and the time, 4.30 pm. “The sky turned pitch dark and I saw a circular cone shaped cloud formation for about 15 minutes. I clicked some pictures and also a video with my smart phone,” says an excited Robert.

 Met officials confirmed that he had indeed seen a tornado, the first one reported in Chennai. “Our officials, who were on their way to Puducherry too experienced some effects of this phenomenon but we confirmed it only after seeing the picture you sent us,” Dr Y. E. A. Raj, deputy director general of meteorology, Regional Meteorological Centre (RMC), Chennai, told the Deccan Chronicle.

According to  Robert, who lives near the coastline, heavy rain and winds measuring nearly 60 kmph  hit the area soon after he saw the tornado. “My friend, who was about 1.5 km away from my house, did not see anything unusual. So the tornado must have been completely localised,” he adds.

 Dr Raj too says there was a definite disturbance during the time mentioned on ECR Road. “We not only encountered intense weather, but our officials, who were travelling in a car to Puducherry  felt the vehicle being jolted to the left of the road. It may not have been an intense tornado as the funnel clouding did not extend to the ground, but  it was unmistakably a tornado,” he concludes.

Puerto Lopez in Columbia the New wettest place in the World and revised Top 20 wettest places...Taken from Pradeep's Blog.

Information provided recently by IDEAM (Institute of Hydrology, Meteorology and Environmental Studies), the Colombian meteorological service, indicates that one of his official sites called Port Lopez de Micay in the Department of the Cauca, pacific region has an annual average rainfall of 12,892.4 mm for the period of April 1960 - February 2012

.

Nevertheless, there are important lagoons in the record from 1960, specially during the period 1968-1979. Despite this it there exist complete records of 31 years in total (until 2011) and in the records only they are absent four months from 1991. Taking the average for these 31 complete years of information the annual average really works out a bit higher in 13,466.3 mm. The was most rainy year a 1984 with an amazing quantity of 23.818 mm (937.72") and the driest with 6.195 mm (243.90'') in 1980 (both years with complete information).

Almost as this there is incredible the number of days of measurable rainfall that totalled 353 days in 1984 and 355 days in 1985 (with 19.444 mm/765.51 ") that were registered. Almost two years of daily rains. The rainfall falls more or less uniformly throughout the year of approximately 899 mm in February to 1197 mm in May. The most rainy month of which witness is had was an August, 1984 when one measured 3015 mm.

Ironically, for years the site of Lloro, Colombia in the Choco Department of northwestern Colombia has often been referenced by numerous publications, including WMO official reports, as perhaps being the wettest location on earth. This was based upon a study published in 1992 by a Mr. Jesus Eslava from the University of Bogota. He researched a site known as the Lloro Granja Agricola (Lloro Agricultural Farm) where an average of 12,717 mm (500.67”) was measured between 1952-1989. This site, however, was not an official IDEAM location, unlike Puerto Lopez. The actual town of Lloro has an average of only 7,559 mm (297.60”) for the 1971-2000 POR. So the Colombian towns Quibdo and Tutunendo are actually considerably wetter than Lloro (with annual average precipitations of 10,749 mm/423.19” and 11,394 mm/448.58” respectively).

The World record rainfall for 1 minute is 31.2 mms, 1.23 inches at Unionville, MD, USA. 
An obscure old French scientific document has recently come to my attention that seems to confirm the validity of the Barot measurement (actually 38 mm/1.496”) in one minute on November 26, 1970.
The World Record rainfall for 5 mins =51.5 mms at Alamogordo, New Mexico. June 5th 1960.
The World record rainfall for 1 hour = 420 mms Cherrapunji, June 16th 1995.
The World record rainfall for 24 hrs. = 1825 mms, 71.8 inches at Reunion Island
The World record rainfall for 48 hrs =  2490 mms, Cherrapunji, 15-16, 1995.
The World record rainfall for a 72 hr. period = 3932 mms on the French Island of Reunion


*On June 16, 1995, Cherrapunji recorded 42 cm rainfall in just one hour exceeding 
the world record of 30.5 cm held earlier jointly by Holt, MO and Kilauea sugar plantation 
(Randall et al, 2007). During June  15-16, 1995, same station reported 249 cm rainfall         
(Pai and Guhathakurta, 2007), crossing  48-hour world record of 247 cm of Aurere,                     
La Reunion, occurred during January 8-10, 1958

26 July 2005 ..
>1 hour highest rainfall at Mumbai Scz : 190.3 mms (3.30 to 4.30 pm)

In 1974 it had rained 24,555.3 mm (i.e. 80.56 feet – i.e. 966.74 inches).  The rainfall in 1974 at Cherrapunjee was the highest recorded annual rainfall in any one place in any one year in the whole world.  On 16th June 1995, it had rained 1,563 mm  in 24 hours (i.e. 5.12 feet – i.e. 61.53 inches).

Cherrapunji does hold the record for the wettest month on record, recording 9,299.6mm in July 1861. Actually, between 1860 and 1862 Cherrapunji was incredibly wet; between August 1st 1860 and July 31st 1861 (which overlaps parts of 2 wet seasons) 26,467mm rain fell. In the calender year 1861 22,987mm rain fell, of which 22,454 fell between April and September.
