1. Four Reasons for heat wave
Now if read the above 4 points and co-relate to the image, u will understand the reasons for the increase in Temperature.
2. High Winds at Pamban – Rameshwaram belt tonight also partly in Vedaranyam – Kodiakkarai region
3. How will be the coming week in Chennai and other parts of state.
For coastal areas like Chennai, Pondy, Cuddalore etc, today (friday) will be the peak from tomorrow the strong land breeze will be absent though it might not dip down directly to 35-36, the temp might fall to 37 C. Assume today we are seeing 41C tomorrow Chennai will see drop to 37 C. From monday / tuesday the temp will drop to 35/36 C.
Interiors like Salem, Karur, Trichy, Madurai will all continue to sizzle at 40 C even in next week. For them either side its land breeze and week easterlies / less winds will make these area heat more with temp remaining around 40 C.
We can see how dry these winds resulting in humidity to dip to 25% at around 12 noon the lowest in this year.
4. How will temp be on voting day in Chennai on 6th April
Next week the land breeze will be absent. Compare this pic with the one in the 1st. You can understand why there is fall in Temperature in the coastal areas. You can also see the Depression gone and return of easterlies in Bay of Bengal.
5. Hottest places in India in last 2 days
Some of the places in Tamil Nadu figured in the Top 25 hottest places of country (only observatories considered.)
Delta and North Interior Tamil Nadu like Villupuram, Tiruvannamalai are getting rains. Even Chennai (KTC) will get on and off rains. Other interiors districts like Trichy, Salem, Karur, Madurai will also get rains to name a few. But the real action shifts to Western Districts close to Kerala. Kerala, Nilgiris, Kovai, Kanyakumari, Nellai, Virudhunagar, Thenkasi, Dindigul, Tiruppur, Kodagu, Chikmmagalur all located perfectly for widespread Thunderstorms with convergence from west and east winds. Even Erode will get good rains.
Chennai and KTCC on and off small spells of rains today. The rains will be of less intensity for next two days and again rains will pick up from 9-12 that too will be on and off rains.
Delta will see good rains 9-12 period. Might turn out to be heavy ones as well. More on that later.
