The Bahrain government is expected to lift the state of national safety on June 1, while some political societies and outlawed opposition groups have threatened to return to the streets.
The U.S. embassy posted on its website maps of the planned protests until June 8 in several Shi'ite dominant villages.
"There is no indication that U.S. citizens are being threatened or targeted. Spontaneous demonstrations and violence are still taking place and the host government is actively conducting security operations," the U.S. embassy said in its advisory.
The British Foreign and Common Wealth Office said they were aware of the planned demonstrations starting from Wednesday.
"British nationals travelling within Bahrain should maintain a high level of security awareness, particularly in public places and on major highways," the British embassy said in advisory on Tuesday e-mailed to its citizens working in Bahrain.
The Philippines embassy on Tuesday also requested its nationals to refrain from going out "if you do not have anything important to do." The advisory posted on its website provides details of planned protests on Wednesday and June 3.
