-Heavy weekend rains in the Maximum City continued into Monday 9 July. The deluge delayed train services, wrought traffic havoc, and caused city-wide waterlogging. But despite the downpour, Mumbai kept to its feet with water receding faster than usual and its lifeline — the local train — running on all four routes, albeit with delays.

2018: Silver lining: Mercury dips, more relief in days to come
Delhi received its heaviest spell of rain of 2018 on July 13 when Safdarjung recorded 53.6mm. Ridge recorded almost 119mm of rainfall in 24 hours.
Around 3pm the dark clouds opened up and torrential rain lashed the capital, flooding the streets and bringing the temperature down by 10 degrees to 25 degrees Celsius. By 5.30pm, the Safdarjung observatory, whose records are taken as the base for Delhi’s weather, had recorded 53.6mm of rainfall. The Ridge logged the highest rainfall during the period with 118.4mm.
Before the downpour on Friday, Delhi had received a total of 64.3mm of rainfall since the beginning of July. The average for the month is 210.6mm.
The maximum temperature recorded in Delhi on Friday was 34.2 degrees Celsius, two notches below the normal for this time of the year.
The other weather stations in Delhi recorded moderate to heavy rain, with Ayanagar receiving 71.4mm of rainfall, while Lodhi Road and Palam logging 44.2mm and 14.2mm, respectively, till 5.30 pm. The precipitation was at its most intense between 3pm and 4pm, and while the rainfall lessened after that.

2018: Expect more rain, temperatures likely to drop further
After a dry 15 July, Delhi witnessed a return of monsoon showers on 16 July with light to moderate rain recorded in most parts of the capital. The showers lead to waterlogging and traffic snarls — especially during the afternoon. The capital received 32mm of rain at Safdarjung till 5.30pm Overcast skies were a feature throughout the day as maximum temperatures were recorded at 34.1 degrees Celsius — one notch below normal for the season.“Mainly northwest Delhi was affected on Monday.” said Kuldeep Srivastava, scientist at the regional met office. According to met office, areas under Palam, Lodhi Road, Ridge and Ayanagar recorded 25.2 mm, 30.8 mm, 38.6 mm, 1.7mm rains respectively during the same period.

Mount Abu, 770 mm rain, 2017
Mount Abu scales new peak
Mohammed Iqbal JAIPUR, JULY 25, 2017
It poured:Life was thrown out of gear as it had rained incessantly for the past two days. Receives 770 mm in 24 hours, flood-like scene in Rajasthan
The desert state of Rajasthan may want to permanently ban the cliché, ‘like the deserts miss the rain,’ as heavy downpour for the third consecutive day led to flood-like situations in Sirohi, Jalore and Pali districts.
The State’s lone hill station, Mount Abu in Sirohi district, received an unprecedented 770 mm of rain in 24 hours. Statistics show that until 2010, the 100-year record for a single-day of rain in Mt Abu was 653 mm in 1992. The only comparable deluge after was a 453 mm downpour in 2015. According to A.K. Srivastava of the Indian Meteorological Department (IMD), Pune, this was “possibly” the maximum rain ever received in the region.
In comparison, the torrential rain that brought Mumbai to a standstill in 2005 was 944 mm and 644 mm on July 26 and 27, whereas Chennai was brought to its knees in 2015 with a cumulative November tally of 1,049 mm.
A rise in extreme rainfall events, according to experts, is the consequence of a spike in temperatures across India in recent decades, and its effect on the monsoon. “Mt. Abu being hilly may not see a situation like Mumbai. But it is now well established that these rain records are a fall-out of global warming,” Mr. Srivastava said. Mount Abu is at an elevation of 4,000 ft above sea level.

Hot days return:With the temperature soaring, it is a challenge for the staff at Amirthi Zoo in Vellore to provide enough water for the animals.C.
Attributable to weak southwest monsoon activity, say officials
After several days of pleasant weather, the temperature has started to soar in the Fort City in the last few days. The temperature touched the 40-degrees Celsius mark on July 23 for the first time in several days.
According to the Meteorological Office, Vellore, Monday recorded a maximum temperature of 39.9 degree Celsius. The mercury level has been rising in the last four days.
The return of hot weather has surprised many residents of the city.
After recording a temperature of 36.6 degree Celsius on July 20, the mercury level started to soar, touching 38.5 degree Celsius on July 21, 39.5 degree Celsius on July 22 and 40.1 degree Celsius on July 23.
This, according to officials, was due to weak southwest monsoon activity. Due to insufficient rainfall this monsoon, the temperature has been increasing. In fact, the temperature level has been abnormal in July and it could worsen if there is no rain.
26th July
Mumbai, 944mm rainfall/ 2005
July 26, 2005. In 2005, Mumbai had recorded up to 944mm rainfall in 24 hours.
The rainfall event over Santacruz (Mumbai, India) on 26–27 July, 2005, was of unprecedented intensity and accumulation in a very short duration. Prior to the occurrence of this event, the monsoon was in its break phase from 19 to 22 July. A low-pressure area formed over the northern Bay of Bengal (off the Gangetic West Bengal and Orissa coast) on 23 July and persisted for a period of 2 days. It became well marked on 25 July, and then started moving inland in the westward direction. During the 24-h period of 26–27 July, 2005, Santacruz received a record high rainfall of 94.4 cm. The event was highly localized, which can be gauged from the fact that Colaba in south Mumbai, around 24 km from Santacruz, received an accumulated rainfall of only 7.3 cm, during the same 24-h period.
Most of the operational numerical models failed to predict this extreme event. In one of the previous studies, Vaidya and Kulkarni (2007) reported that their model failed to simulate the 38.1 cm of rainfall that occurred during 0900–1200 UTC, 26 July 2005, due to the coarse grid spacing (40 km). In another modeling study, Deb et al. (2008) investigated the impact of the Tropical Rainfall Measurement Mission (TRMM) Microwave Imager (TMI) sea surface temperature (SST) on the simulation of the heavy rainfall episode over Mumbai, using two different mesoscale models. They found that the intensity of maximum rainfall around Mumbai was significantly improved with TMI SST as the surface boundary condition in both the models. Using the Weather Research and Forecasting (WRF) model, Kumar et al. (2008) reported that an interplay of various factors like the low-pressure area over the Bay, strong moisture convergence, and meridional temperature gradient might have contributed to an event of such magnitude.
A major feature of this event was that around 65 cm of rainfall was accumulated in a span of 6 h, which amounts to 70% of the total rainfall being accumulated in just 25% of the time, hinting at the strong intensities of rainfall that might have occurred during the period.
During the Indian monsoon season (June through September), especially in the months of July and August, many locations along the west coast of India (towards the windward side of the Western Ghats) receive heavy rainfall. The strong moisture-laden westerlies from the Arabian Sea interact with the topography, causing heavy precipitation over this region. The other important factors leading to such intense rainfall events are the mid-tropospheric cyclones, and organized convection in the tropical convergence zone (e.g., Krishnamurti and Hawkins 1970; Benson and Rao 1987; Ogura and Yoshizaki 1988). In the past, heavy rainfall of the order of 50 cm/day has been reported at various locations along the Indian west coast (Dhar and Nandargi 1998; Kulkarni et al. 1998).
In a previous study, Doswell et al. 1996 emphasized the importance of ingredients-based methodology for flash flood forecasting. They suggested that all flash flood events have some basic ingredients in common, whose presence can be used as potential indicators of heavy precipitation. They reported that heavy precipitation rates involve high values of vertical moisture flux, associated with high vertical velocity and substantial amount of water vapor contained in the ascending air. The other important factor responsible for heavy rainfall rates is the precipitation efficiency, which in turn is a function of the relative humidity of the environment, and several other factors like wind shear.
