Severe Heat Wave Likely In Odisha From Apr 25, Bhubaneswar-Cuttack To Sizzle At Over 40 Deg C

With the gusting wind speed going to remain at around 40-45 kmph, and when there are weather ingredients that favour the formation of supercell thunderstorms, the State's coastal and northern region seem favourable to lightning and norwesters till April 21.

However, there will be a change in wind from the coming weekend. The nip in the wind will trigger the heatwave attack on the State. Model predictions hint heatwave gripping largely some places in the State in the coming week.

Lightning Prone Dists

As per the model data of GEFS(Global Ensemble Forecast System), the following districts are predicted to record lightning and thunderstorm in the following days and hours.

• Hailstorm probability forecast for districts like Mayurbhanj-Keonjhar, Malkangiri-Gajapati on April 21.
• Lightning-cum-thunderstorm in districts like Puri, Nayagarh, Cuttack, Khordha, indcluding Bhubaneswar, Jagatsinghpur, Bhadrak, Jajpur, Kendrapada, Keonjhar, Mayurbhanj, Balasore, Sundargarh and Bolangir on April 20.
•  The forecast time for Apr 20 is between 2:30 PM - 8:30 PM.

Blast Furnace Climate  

As per the NCEP and ECMWF forecast, the wind will change direction from the coming Sunday. The wind direction and speed will take a turn.

While wind will start blowing from the southeast in the coastal region, the direction in the western and northern will be from the north-northwest.

Moreover, from over 22kmph wind speed in the coastal region currently, the models predict the wind speed slowing down to around12kmph.

As a consequence, the mercury over the whole landscape of the State will shoot up from Sunday. And the aggregate will pinch the State hard from April 26-29. 

The forecasts show some places in Sundargarh, Keonjhar and Angul recording around 45 deg C between Apr 25-29.

The model data shows intense heatwave like conditions prevailing in the State during the week of April 28-May 4. There is a forecast of easing of the heatwave in the State during the week of May 5-11.

However, coastal places like Gopalpur, Paradip, Dhamra etc will stay immune from the mercury fury. 

Bhubaneswar-Cuttack Climate 

The forecasts by IMD and NCEP show that the Capital City will record over 40 deg C in the following days. The time period will be between 12PM - 2PM.

•  April 24 
• April 25
• April 27
• April 28
•  April 29.

Similarly, on the same date mentioned above, Cuttack city will also record a maximum day temperature of over 40 deg C.

Low Pressure

The prediction of CGEPS-IGPP shows the probability of cyclonic circulation in the south Andaman seas between Apr 21and 27. But the parameters give no clue about the system's intensification. 

No cyclonegensis in the Bay of Bengal or Andaman seas till May 11.
