Definitely a time to pray and seek His face earnestly.
2 Chronicles 7:13-15New King James Version (NKJV)
13*When I shut up heaven and there is no rain, or command the locusts to devour the land, or send pestilence among My people, 14*if My people who are called by My name will humble themselves, and pray and seek My face, and turn from their wicked ways, then I will hear from heaven, and will forgive their sin and heal their land. 15*Now My eyes will be open and My ears attentive to prayer made in this place.
