Con il caldo e il sole torna in Ticino l'incubo ozono e, prontamente, le autorità scendono in campo, invitando i cittadini a limitare gli sforzi fisici nelle ore più calde della giornata. Nella Svizzera italiana l'ozono ha raggiunto un picco di 262 microgrammi per metro cubo giovedi a Mendrisio (A2), quando il limite massimo dell’ordinanza federale è di 120. Anche venerdi ci si attendono valori simili, con ulteriori superamenti della soglia d'attenzione.
I rilevamenti in Ticino
Non è prevista l’emanazione di una
allerta canicola anche perché nel fine settimana sono attesi temporali che rinfrescheranno e ripuliranno l'aria. Valgono comunque gli
inviti che ogni estate vengono diffusi. Le temperature, secondo
meteoSvizzera, toccheranno oggi, venerdi, e domani, sabato, i 31 gradi, per poi diminuire nei giorni successivi.
