(Eric Leister in
Accuweather) The yearly advance of the southwest monsoon is vital to both
people and agriculture across India and rest of the Indian subcontinent.
The normal onset of the
southwest monsoon occurs during the second half of May across Myanmar before reaching
southern India at the beginning of June.
This year the monsoon was
actually several days ahead of schedule reaching Myanmar, but it has stalled
over the Bay of Bengal during the past week.
As a result, the onset of
the monsoon in southern India will likely be up to a week late across parts of
the south, but the beneficial rains are forecast to increase during the second
week of June.
The heaviest rains are
expected to be focused from the western Ghats to the west coast during this
time. Scattered rains are expected across the southeast.
With an El Nino expected to
build during the second half of the year, rainfall across central and northern
India could be impacted greatly.
As a result, the northward
advance of the southwest monsoon is forecast to be delayed for most of central
and northern India allowing temperatures to soar well above normal for much of
the month of June.
Several long stretches of
temperatures over 42 C (108 F) are possible in New Delhi and the surrounding
region.
Long-range forecasts are
for below-normal monsoon rainfall in these areas, stretching into neighboring
Pakistan. Concerns continue to rise that a drought will develop across
northwest India and Pakistan as a result of prolonged dry and hot weather
followed by a weak monsoon.
India is a large supplier
of rice and cotton globally, and these crops could suffer greatly as a result
of the impending hot and dry conditions. According to Accuweather.com Commodity
Weather Expert Jason Nicholls,
Farther south, the monsoon
should arrive before the full impact of the oncoming El Nino occurs. The best
chance for a near-normal monsoon will be in the southwest.
With rainfall expected to
be below normal for much of India during this monsoon season, any rainfall from
tropical cyclones would be increasingly important.
The Bay of Bengal will
likely produce several tropical cyclones during the summer months as a
near-normal season is anticipated. Although flooding is always a threat from
landfalling tropical cyclones, this will be offset by the positives of rainfall
during a stretch of otherwise below-normal rainfall.
